Back ports (USB, ethernet) stopped working, front ports partially working

Q: Back ports (USB, ethernet) stopped working, front ports partially working

Vista Ultimate 64-bit, ASUS Rampage Formula motherboard, USB mouse and keyboard connected in back ports.

Two things happened: Avira antivirus warned me of some threats which I either ignored or deleted. Windows Update had some updates ready (although I'm not sure if it updated).

I turned off my PC for a couple of hours, turned it back on and realized that my USB keyboard was not working on the password screen.

I eventually unplugged it from the back and plugged it into the front, where it worked. However, my USB mouse did not work when plugged into the second front port, nor did it work when plugged into the front port in which the keyboard worked.

I accessed System Restore using my keyboard and restored to one day previously. When it finished, both keyboard and mouse worked, although I got a pop-up message alerting me that the "drivers for your device could not be installed." When I clicked "OK," the mouse stopped working again.

I have checked BIOS and both mouse and keyboard are recognized, so it does not appear to be a hardware issue.

I'm really puzzled with this one: Vista shows neither my digital camera or my MP3 player plugged into my USB ports. However, my HP thumb drive shows up fine in the same ports in the front of my machine. Why would a static memory drive work fine but two capture and playback devices Not work?

Any thoughts? Thanks for any help.

A:USB ports have stopped working - partially

Please plug in the digital camera and the MP3 player.
Then check Device Manager to see what it has to say about the 2 devices.
To get to Device Manager, go to Start and type in "devmgmt.msc" (without the quotes) and press Enter.

Let us know if the devices are detected.
Let us know if they have any problems (red x's or yellow !'s)
Let us know if there are any unknown devices.

You might have to open up your case, trace back the cable, and re-plug it. It could be detached, or the USB controller on the front ports could be fried somehow too.

I have an Inspiron M531R-5535 and about 3 days ago I noticed that none of the USB ports were working when I tried to back up my phone.  The next day, the Ethernet port failed.  It is not the wire, as it works on a different computer.  My WIFI is working fine, but it is really slow, so I would love to be able to get the port working again.  I am extremely unknowledgeable about computers, so any advice on this would be greatly appreciated.  Thanks!

Based on this info does it seem likely that the front ports themselves are faulty?

Hey
Today i just bought some ear phones, with a connected mouth piece. Problem is that my two front ports are dodgy for the microphone and headphones. So if i put the jacks from my headset into the back, i have to take out my speaker input.. Is there any way i can have the speakers in, and the headset and revert back to each without going at the back and changing them? Any help appreciated
Thanks
 

A:Headset not working, front ports not working

First, its possible inside your computer case, there is just a loose cable that is causing the problem with the front jacks on your computer. Check inside, right behind where the earphone jack is for a cord running to somewhere on your motherboard or Sound card.

If that dosn't work,
Do you have a CD/DVD player with a earphone jack and have you tried that?
Assuming its the port that is bad itself and not just loose, you could check in at radio shack, bestbuy, or newegg.com for a cord that splits the output. If you get lucky you might find one with a chanel select that will allow you to swap which recieves the output.
The other option, from radio shack I got a Bluetooth USB adapter for $20 and a good pair of BT earphones, again purchased online for cheap (I recommend samsung BT500 earphones).

Another alternative, my speakers have a earphone jack in them as well (the computer speakers, as well as the reciever I currently have my sound card plugged into).

If you have a quality home theater set up, for $80 on new egg you can pick up a good soundcard with optical, Coax, and AV out which you plug into your home entertainment center that again will allow you to use headphones.
Good Luck

Hello!

I have a Gigabyte motherboard in a Antec Lanboy case. The case has two front USB ports. The USB ports do not work with most devices. For example if I plug in a USB key or a webcam I get the balloon that says "the device may not be recognized". But if I plug in a keyboard, mouse, or RF receiver, it works. Could it be that the front ports are USB 1.1 or are underpowered? I've read that Gigabyte USB connections are a bit different, but I've checked them before and are as illustrated in the manual By the way, I'm on XP SP2 and the USB connections from the mobo are not a single block - they are individual pins.

Hi there. I recently bought a barebones kit from Tigerdirect. It has usb 3.0 support, and the case I have is a cougar mid-tower case. Everything has been hooked up correctly as far as I know, and yet one of the usb ports on the front of my case does not work.

The connector that went into the motherboard from the front of the case, it yielded to both the usb 3.0 port, and the standard 2.0 port as well. So only one cable was plugged into the motherboard that I assumes powers both of them.

My usb 3.0 works (though I don't get full use out of it because I don't own any 3.0 devices to make it useful) but the standard 2.0 port does nothing at all. Doesn't even give power. I've tried plugging a phone into it, a flash drive, a plug n play device. Nothing. Does anyone know why the 3.0 port would be working and not the standard one?

I should also add that all the usb ports on the back of my case work fine too. It's just this one single port on the front of the case and I can't figure it out for the life of me...

A while ago, my front USB ports stopped functioning. The controllers still show up in the device manager even after reinstalling them (Or at least I think they do, it's one controller to two ports, right?), but whenever I plug in a USB device, even ones that previously functioned on these ports, nothing happens (The LED on my gamepad doesn't even light up.). I've tried scanning for hardware changes. The ports came with the case. The computer is custom built.

System specifications:

Windows XP SP2, using a custom shell <-Have tried uninstalling the new shell and putting default shell back to explorer, USB devices still did not work on the front ports.
Asus A7N8X bundled with nForce2 sound card.
AMD Athlon M10 Processor.
Two hard drives.
One Cd Drive. One DVD Drive.
nVidia GeForce4 Ti 4200 Videocard.

Any ideas are appreciated. It's a total pain to have to find my way to the back USB ports all the time.

Edit: Oh. Wait. Not sure if it actually is detecting three sets of two USB ports, the device manager lists the following:

Universal serial bus controllers
Standard Enhanced PCI to USB Host Controller​Standard OpenHCD USB Host Controller​Standard OpenHCD USB Host Controller​USB Root Hub​USB Root Hub​USB Root Hub​
Does this mean I have to figure out the enigma that is the front panel of my pc case? I hope not.

I noticed these past few days that my front USB 3.0 ports are not working. Whenever I plug a USB 2.0 flash drive into the front ports, the activity light on the flash drive itself does not turn on.

I did clean all old Windows updates using disk cleanup which may have caused the problem.

So far, I uninstalled the USB driver and tried to reinstall the software with no success.
I have attached a picture of a screenshot after the driver installation failed.
Thank you

A:Front USB ports not working, driver problem

Just a couple of questions, how did you reinstall the drivers? Through Device Manager or running from the motherboard disc utility? And did you have any USB devices plugged in when installed it?
Usually if you run the software from the motherboard disc and choose drivers you'll get a list of drivers with check boxes next to them, and any that aren't installed will be unchecked. Those would be the ones you need. The ASMedia XHCI controller is the driver for your mid board header which controls the front USB 3.0 ports and that look as if it's installed fine, so I'd run that motherboard utility and see what it shows up.
Also could you post a screenshot of Device Manager with the USB controllers section expanded.

For what it's worth I have a very similar set up in my back up rig (A10-5800k on an ASUS F2A85-V Pro) and have never got the front USB 3.0 ports working on the BitFenix front panel I added. Not saying we won't get yours working, just that you're certainly not alone with this issue.

Hello,

I have had this computer for over a year, when I initially got it I noticed the two audio ports on the front of the tower were not working. I double checked to see if it was plugged in on the mother board in the right spot, it was. I decided to just leave it before anything else broke, but after a year I love my computer less and am willing to take the risk .

When I plug it into speakers into the front audio jacks (There are two) Realtek HD Audio does not give the message "A Jack Has Been Plugged In". The back ports work fine for the record.

Specs:

Windows XP SP3

Motherboard: MSI 975X Platinum PowerUp Edition

Realtek HD Audio Manager:
Driver Version 5.10.0.5898
Audio Codec ALC888.

If you need any other information please let me know as soon as possible.

Thanks in advance!
 

A:Solved: Front Panel Audio Ports Not Working

Well I got it working after much forum searching!

"Had same problem but problem isn't the chip.
In Realtec Audio Manager, if you hover over the pink and green icons for the front panel you'll probably see they're both set up for speakers or headphones.
To solve you first need to unplug the microphone.
Then click on the 'folder' icon, which is just to the right of where it says 'ANALOG'.
Then make sure you enable fron't panel jack detection and enable the auto pop-up dialog.
Then plug the mic in, and when the pop-up asks tell it that you've plugged in the Mic.
Suggest you disable the front panel detection and the auto pop-up afterwards as it's a right pain.
You can get a similar end result if you use the 'Connector Retasking' facility - just right click on the pink or green socket icon.
Hope this helps someone.
Olly"

I have had my hard drive reformatted recently and installed Windows 7 (from Windows XP). All the drivers and hardware are currently working fine. However, my front panel audio ports(mic and speaker) have stopped functioning.
The front panel ports used to function smoothly in my previous setup. The audio driver installed previously was Realtek HD Audio Driver and the OS was Windows XP.
Currently, I have a generic 'High Definition Audio Device' driver provided by Microsoft.
Is it possible that the front panels have stopped working due to the absence of the Realtek Driver? I read in numerous articles that the front panel ports could be enabled through the Realted HD Audio Manager. Is this true?
Can the problem be solved simply by installing new driver and software or do I have to explore the unknown (for me) realms of computer hardware?

Any help is appreciated! :D

After you do a clean install of Windows 7 or Windows 10 in that computer, you need to install the drivers for its primary devices(chipset, graphics, audio, wireless , ethernet, etc.).
The chipset driver needs to be installed first before any of the other drivers are installed so the Windows operating system can properly detect and configure the computer's devices.

Hi, we've just moved into an apartment and have realized the two ethernet ports in each of our bedrooms aren't working. We contacted our real estate agency, who first told us to "buy a new one", but after some further explanation told us they would get back to us tomorrow on whether it is our problem or theirs. So, in the meantime, I was hoping you guys could offer any help or explanations or things to explore so that we can fix it on our own.

I looked around the internet and found that there is usually a central hub where these wires come together behind a panel somewhere. I've checked all the bedroom closets but didn't see anything. There is another closet with the hot water heater and something else but I didn't see any wall panels. There is another large panel in the wall by the laundry room with the air filter, and above that are a few electric charts and labels that cover something but it says it is dangerous to remove with the power on. There is another closet on our balcony with a cable box inside, but it is locked with a termination lock.

We have cable internet though Northland if that matters.

Hi

I am running Windows XP SP3 on a HP Compaq NX6325.

A month ago I got all 3 of my USB ports stopped working. Device Manager shows each USB Host Controller and the corresponding USB Root Hub as working correctly.

I can uninstall the USB Root Hubs, but the 3 Host Controllers will not allow me to interact at all, i.e. I when I try to update the driver, disable it or delete it then the window freezes until I stop the process.

I have updated the BIOS to the latest from the HP website and made sure that USB is enabled.

Searching the web I have tried a few driver check programs, all of which says nothing about upgrading the USB.

One thing to mention.... from the MS website it states that USB usualy uses IRQ 9 whereas my USB Controllers are on IRQ 19.

Any help gratefully received

A:3 x USB Ports Stopped working

You cannot update...USB controller drivers, those are installed by Windows. If they are damaged, updating won't necessarily overcome that.

Go to Device Manager...ignore the hubs, uninstall each controller...reboot.

Hi,
I've been working on this problem online with HP for over a week. They've given up and are shipping me a box to return the machine for them to fix at the factory. Before I give up the PC for the time it takes them to do that, I thought I'd ask here to see if anyone has already successfully solved this problem.

My computer has stopped recognizing anything that's plugged into any USB port. Device manager says the ports are active and fully powered. We've tried re-installing the USB Root Hubs (anyone know why there are always two of them?) multiple times, upgraded the drivers, and in a last-ditch attempt to make everything like new again we reinstalled the operating system entirely to factory condition after backing up all our data to DVDs.

Still no recognition of anythign in a USB port. Printer says it's installed but nothing will print, flash drives are not recognized, nor camera or iPod. Interestingly enough it doesn't seem to be a hardware problem since the iPod WILL charge in the USB port just won't sync.

Has anyone seen this problem before?

Thanks.

A:Usb Ports Stopped Working

I can't say for sure, but if you've reinstalled the OS and still can't use the USB ports - then it's time for a repair/replacement. It sounds to me as if it's a partial failure of the USB ports (the data channel rather than the power) - but I don't know a whole lot about their construction. Sorta like one of the traces that the data travels is broken, and it's broken before the split to the different ports (but this is only speculation on my part).

I may have seen the same thing at work not long ago - but can't recall the make of the system. As I seem to remember, we shipped it off for repair at the service center.

I plugged my friend's ipod touch to charge from the computer and it did not work and after that none of the ports will work. I tried reinstalling the drivers, restarted the computer multiple times and even ran a virus scan but its of no use. Out of the 3 ports only one says "windows detected a problem with the device", the other 2 wont even say anything. I even checked at the registry keys to see if the USB ports are enabled and they were fine. My warranty expired this December so now I have to pay HP for any trouble shooting.
Is there any simple fix to this solution which I am missing?
Thanks a lot for your time!

A:USB ports stopped working

Two possibility come to mind there may be more of course.

1. A USB port has become physically damaged
2. The port may be OK mechanically and the device damaged the electronics

Hi everybody, I was updating my drivers on my xp desktop, suddenly the devices attaced to ports stopped working. I assume I was downloading a usb port driver ets I cannot remember. Now none of my ports are working (4back and 2 front) I have done the usual device manager check which shows two standard openHCD USB Host Controllers and two usb root hubs, I have tried to uninstall them and reboot (after turning off system restore) no use my pc does not recognise any device connected to the usbs. Checked BIOS nothing obvious. I am considering downloading a new motherboard driver install. Can anybody help me please. Thanks.

My front and rear USB 3 ports stopped working. The rear USB 2 ports still work. When I plug an external HDD into the front USB 3 ports it powers up the drive, but it isn't recognized in Windows Explorer. My USB card reader doesn't light up. Device Manager doesn't show any USB 3 devices, and nothing is showing a yellow x in Device Manager.

Any ideas? The last time I used the front ports was a few weeks ago at most. There have been Windows 10 updates since then, but I don't know specifically when they stopped working.

Hello I'm new to this so I'll try my best to explain the problem. I have a wireless mouse that stopped working, the problem is when i plugged the wireless receiver in the USB port, the computer says "found new hardware" and hardware is installed and ready to use. The mouse works for a couple seconds but then after that they stopped moving, after I restarted the computer, the mouse still stands in the center on the screen, so I tried a different port the same thing happens and if I use the the USB port already the mouse won't even move for a few seconds. Its not the mouse's fault because I asked my neighbor to borrow his mouse(which is USB plug mouse) and the same thing happens just like my mouse. I tried to to see if its the USB devices' problems but I use my flash drive and it works so its not USB device's problem so I'm wondering if some one could help me with this problem.

I was working normally, playing a game, but then suddenly the sound stopped working. I identified that it was the USB ports, not the speakers, that were not working. The computer has 12 USB ports, all of them have stopped working. Is there any way this can be fixed? I ran the TSG SysInfo, but it just came up with this:

I'm guessing it shouldn't do that. Please help me as soon as possible! Oh, sorry if this was posted in the wrong section!

Short story: All my USB ports stopped working. Well actually... not ALL of them.

Long story: The USB ports on my computer consist of 6 ports onthe motherboard, 2 additional ports on my Cooler Master case, and yet another 2 ports provided by an add-on card plugged into my motherboard (in a manner similar to my video card). I am able to use a keyboard and mouse because the 2 ports on the add-on card are still working. The fact that the USB ports on the motherboard AND the ports on the case stopped working suggests that this isn't a motherboard problem. Nevertheless, I need to fix the motherboard and case USB ports because I can't plug in a printer or camera or anything like that.

Well the USB ports on the case IS connected to the mobo, specifically the 9-pin USB header.

But have you checked if onboard USB ports are enabled in BIOS?

hi guys, this problem has been plaguing me for a long time now. tried searching everywhere but none of the solutions seem to be working. My USB ports were working fine until one day when i uninstalled my HP printers drivers and software. It doesnt show any problem in the Device Manager(i.e no exclamation marks) but devices seem to be drawing power from the ports, only windows does not detect these devices. When i plugin any device, i don't get the sound which i usually do nor a popup from the system tray. Plz guys help me out as I;m really really stumped.
Im using Windows Xp Proffessional with SP2.

Look in your device manager and see if any USB devices have show to be not working or not installed. In any case try deleteing the USB Controller and letting Windows reinstall it.

The USB ports on my friend's laptop (HP Pavilion DV6000 running XP Home) randomly stopped working about a week ago. He hasn't made any changes to the system in some time. When you plug in a USB device, it gets power, but the computer doesn't recognize it. Here's what I've tried so far:

- Uninstalled all USB drivers from the device manager
- Unchecked the "allow computer to turn off this device" option under power management
- Installed newest version of the nVidia cihpset
- Made sure that USB is enabled in the BIOS
- Tried a registry fix found here - http://forums.techguy.org/hardware/673766-usb-ports-suddenly-stop-working.html

Unfortunately, nothing has worked. What worries me is that I also tried using an Ubuntu live cd, and no USB devices were recognized there either. I'm thinking that this might be a hardware problem which can't be fixed, but does anyone have any ideas on what to try before I declare this problem unfixable?

I am new here and not sure if this post belongs here, if not please point me in the right direction.  
About five month ago I built a pretty basic computer. I have been using a pretty crappy tower since then and today upgraded. I switched out all the internals and set everything up in the new tower. After booting up into windows (8.1) anything connected to any USB port would become unresponsive. Although every minute or so the number lock light would flash signifying the keyboard was receiving power for a split second. I shut down the computer and booted into BIOS and the keyboard worked perfectly. I also checked to make sure the USB ports were enabled in one of the BIOS pages. Even after this the keyboard and mouse refused to work after entering windows.

   You might want to try re-installing your motherboard and chip set drivers, it couldn't hurt.
