Comm Ports don't show up on Device Manager

Q: Comm Ports don't show up on Device Manager

I am running Windows XP home. I was able to view comm ports earlier today in device manager but I had to re-boot my PC and now the Comm Ports do not show up in device manager. Does anybody have an idea as to why this might be happening.

Thanks,

Greg

Preferred Solution: Comm Ports don't show up on Device Manager

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi,

Opened up Device Manager to look at settings for the various Com "Ports" in use and just can't see any listed. Here's a snap of what I have.

Where do they show, or how can I make them show up ?

Thanks,

Two of my USB external Hard drives, a Fantom 600 GB and a Western Digital My Book 500GB cannot be seen in My Computer. I can see them in Device Manager and that says that they are working properly and the drivers are up to Date. In Disk Manager the 2 external drives had a black bar unlike the other drives which had blue bars. The 2 external disks had a number assigned to them but no letter.

I have tried diskpart in the command prompt, was able to assign a letter, then had to format the drives and they did show up in My computer as valid empty external hard drives with the correct amount of space on them. But when I tried to recover the backed up data for one of the disks (less than a third of the capacity of either drive) they went back to not being recognized by My Computer ans in disk manager had a black line with no letter again.

I just went through that process again, got both drives back and tried to recover the backed up files to my Fantom drive and lost the Fantom drive once again.

I am attaching screen shots of my current My Computer (Computer in 7) Device Manager and Disk Manager. In Device Manager you can see the Fantom. The My Book is the WD 5000AAV. In Disk Manager the My Book shows healthy with Disk 1 and the letter L. The Fantom is Disk 2 with no letter and a black bar. In My computer, the My Book is there but not the Fantom.

A:External drives show in Device Manager & Disk Manager but not Computer

Hi Dick1030,

Welcome to Seven Forums.


Please do as follows:

1. It is unusual for the System Reserved Partition to have a drive letter. Please remove the drive letter.

2. Please remove (always Safely Remove) all the external drives including any card reader and do a drive cleanup as indicated here. http://www.sevenforums.com/hardware-devices/298744-usb-thumb-drives-not-recognised-not-drive-letter.html#post2477076 It will clean your system of all non-present devices and you will be starting with a clean slate.(Incidentally this can resolve many drive letter assignment confusion of Windows OS, as you can see in the referenced thread.)

3. After you reboot on completion of the drive cleanup, plugin only your WD My Book and the Fantom drive. As you plug-in the driver for each device will be installed ab-initio. You can watch it.

4. Now take a screenshot of the Disk Management and post. While taking the screenshot, click on "Show/Hide Console Tree” and “Show/Hide Action Pane” buttons on the toolbar on top to hide those and also pull up the center partition line up as much as possible so that we get a clear and full view.





5. Also tell us whether you are sure that you had formatted the Fantom drive and it contains data and whether you want to recover the data..


(Your statements and the screenshots are so confusing - atleast to me - it is necessary that you do the above and restate the problem.)

Hello,
I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more

I have tried downloading the current audio drivers for the computer but every time I try to install the driver, I get an error that says the device couldn't be found.

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the icon....it gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is. I decided to do another reformat on my hard drive. This time, I ignored the optional updates. I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this.

1) Check to see if the device is hidden. For this, click show hidden devices under View, then expand all the nodes under device manager. Uninstall any entries which appear grayed out, then restart. Then try plugging your external device to the computer and see if it works.

2) Make sure that in the BIOS the ports are enabled and set to 'auto'.

3) If that does not work, try installing the drivers for your device manually.

Hey lads,

So I am not a computer genius, but I am not completely clueless and I have been struggling with this issue for a while now. I have searched high and low trying to find a solution.

My computer will recognize the two usb ports on the rear of my cpu (I also have 2 on the front). The two on the front however are not only not recognized in Device Manager, but when I plug a device such as my thumb drive or mouse it seems to turn the power off of the rear ports. Eg. If my mouse is plugged into one of the USB ports on the rear, and I plug my thumb drive into one of the front ports, my mouse will completely turn off and will not return until the other device is unplugged and Windows is restarted. I am not sure if this is a driver or hardware issue or what, but any help would be much appreciated as I am a student who has very little money to replace things.

Computer Specs as follows:

Asus Computer with Intel Pentium 4 CPU, 2.40GHz
512 MB of RAM
Windows XP PRO SP3
NVidia Geforce 100/200 graphics card

I am not sure what other info you may need, but if you ask I will tell.

How do we get the COM Ports back?
 

A:COM Ports Missing - Device Manager

Be sure that the port is enabled in BIOS. Try removing it from Device manager and rebooting for reinstallation.

If BIOS allows it, and the above does not work, try changing the IRQ or memory used by COM1.

Hey!
I'm using an dell inspiron laptop with windows vista. Few days back, installed windows Xp professional successfuly. The main purpose I installed xp was to program a microcontroller via the com ports. But to my surprise the com ports were not listed in the device manager in XP! Any help??
 

A:COM Ports not listed in device manager

Are you sure the laptop actually has a COM Port? Finding a laptop with a COM port newer than a Pentium III model is rare, as they have been all but replaced by USB.

Make sure you're not confusing a VGA port for a COM port. Same size and shape but the VGA has 3 rows of contacts (15 total) instead of 2 rows of contacts (9 total) for a COM port.

If the laptop shipped with Vista I'd be surprised if it did. Even many 4-5 year old laptops that shipped with XP don't have a COM port.

If it does have a COM port, check in the BIOS to make sure it's not disabled

I have a system with an Intel DG31PR mobo.

I installed a hard drive and setup Win XP. After updates I noticed a few issues, namely that none of the USB ports work. I also noted a SM Bus Controller in the Device Manager that would not update.

I went online and found the chipset drivers for the mobo. When running it removes and installs new USB controllers, but the setup keeps stalling during the first installation of USB 2.0 controllers. I left it running for hours before ending the processs. Now I have a USB root hub with no driver listed in the DM. If I try to run the driver setup again it picks up right where it left off but still stalls. I have tried uninstalling the USB controllers and root hubs, but any attempt to remove them or even to scan for hardware changes causes DM to freeze up, and then the computer won't shutdown without a hard reset.

Is this a bug in the chipset drivers? I have considered upgrading to Vista (as the computer sans hard drive has a key for it) The hard drive was part of a OEM HP system with a dead mobo. I formatted the hard drive to put in this system.

What to do, what to do....

Recently, this is what I did.

2) partitioned the HD

3) reinstalled the OS and upgraded to XP SP2 from SP1.

Now in the Device Manager, there is no section for "Ports"



In Device Manager, originally when I clicked "show hidden devices", under "Non-Plug and Play Drivers", there were warnings/error notices next to "parport" and "serial".



I can't print or sync my Palm. Other USB stuff works. Strangely, when I installed the Palm Desktop software, it let me sync one time. When I went into the settings to set up my e-mail sync, I got an error that the COM 1 port wasn't available and it switched to COM 3. I won't sync now.

I tried deleting the "parport" and "serial" drivers and they don't (immediately) return when I restart or "scan for hardware changes", but eventually show up again.

I am working on a computer that needs to send information out a USB port to a circuit board that controls access to a building. For reasons I won't list here plugged into the USB port is a usb to serial converter. This USB to Serial converter has a short and it is difficult to keep the link up. I have another USB to Serial converter (a Belkin) that doesn't have a short (green light indicating connection stays on). However, the information will not reach the controller when I am using this converter (same USB port). By the way I have loaded the driver for this USB to Serial converter.

When I look in the application that is sending the data, the selection is set on Serial 232/USB. I looked to see the serial port that is specified and it is "6". Is it possible that when I installed the driver for this Belkin USB to Serial Converter that it assigned it a different serial port. If so, how do I find out which one? (XP Pro OS). I'm thinking if I can tell the app which port to use for the new Belkin converter I will be back in business.

A:Comm Ports in XP

You need to remember that both Serial Com & USB have line-length limits. That is, the devices must be close enough to not exceed the limits.
I don't think using a USB-to-COM converter uses a COM Port number. This assumes that you use the exact same converter at both ends.

Computer-1 <----> USB_signal <----> Serial_COM_signal <----> USB_signal <----> Computer-2

Note that USB does not have "ports" so that makes port assignment irrelevant. This is assuming you are using a USB connections on both computers.

IF you are using:

Computer-1 <----> USB_signal <----> Serial_COM_signal <----> Computer-2

Again, port assignment is irrelevant. Whatever COM Port you plug into at Computer-2 will be the one, and the Port# should be labeled at the connector.
Did you open Device Manager, Ports tree, and see what it has listed? (see screenshot)

Now if you have a Belkin USB/Serial Converter Utility that was installed with the driver, you should look at that. If you do NOT have such a utility, then the Belkin does not configure anything (no Port assigned).

I took a lightning hit to my Amatuer Radio station which also was tied into my computer. Since the hit I have not been able to run anything off of com port 1. Windows reports in device manager that all ports are working properly. My question is, even though Window 7 reports that all ports are working properly, is it possible I could still have a bad port on the mother board?

Thanks in advance
Marv

A:Comm Ports

Yes it could still be bad since Windows can only see the digital side of the port.

PC is Windows 7 Pro 64bit, MSI Z77 MPOWER motherboard.

I'm attempting to flash a bootloader to my 3D printer, which requires connecting it to my PC via USB and using the Arduino software. Unfortunately when doing so the Com ports menu in Arduino was greyed out no matter what I tried and so I couldn't select the printer or USBasp device.

On further investigation, I discovered that the COM & LPT section isn't present in my Device Manager, and using "mode" in CMD returns CON info but no details on COM & LPT ports at all. I went into the BIOS and ensured all USB-related options were enabled, which they already were, and additionally I updated the drivers for both of the motherboard's USB 3.0 controllers. Still nothing.

I feel at this stage I must be missing something stupendously obvious, but I'm drawing a blank. Can anyone suggest what's going on/a fix?

I'm about to explode with frustration!

Problems started when USB ports seemed to spontaneously stop working. Then Device Manager window is empty. Nothing shown at all. Also My Computer takes ages to load and system often seems to hang

A:Device Manager empty. USB ports not detecting

I have a partial resolution to my problem!

Thanks to everyone who offered help.

First option was check that PuNP was started - OK. Later I discovered that Universal PuNP must NOT be started!

Second option was Aproposfix which I assume is to get rid of some specific spyware/adware/malware.

Third was I tried editing some permissions in the registry but I didn't really understand what I was doing.

Fourth was I ran sfc/scannow - whatever that is!

Also system was hanging on startups and shutdowns, sometimes needing the big switch to get out of it. Now you can click on IE or My Computer or Control Panel and it takes ages for them to load. Usually I find myself with about five instances of each all loading at once.

Frequently web links won't work. The only thing I can do is avoid a left click - use right clicks to save shortcut and then paste it into address bar. I have tpo switch back and forth betwen web browsers using teh Task Manager. OIften the Task Manager itself freezes with the button still "pressed down".

I've also been using my SpeedUpMyPC utility which allows you to give CPU priority to a particular window. A combination of this, Task Manager and a hell of a lot of patience just about keeps me going

Oh, and I updated all my chipset drivers along the way.

MY DEVICE MANAGER WINDOW IS NOW FULLY POPULATED!!!!!

Oh joy! The printer is working too. The solution? It was to do with permissions. I had to spend a lot more time and give a lot more ... Read more

I've recently taken over a new computer at work and did all the windows updates since last year, this computer was not connected to the internet. The computer is a IBM XP Pro.

As I go to install my printer (2 different ones) the software won't install, so I finally figured out the problem. The ports are missing in the device manager. I've gone to 'show hidden devices' and still not there.

I've read through a few of the posts here, and there was suggestion that I should go into the BIOS and set LPT1 to EPP/ECP, I cannot get into the BIOS, i've tried all the F-Keys, Esc, Delete, Insert and whatnot and no luck. I've also tried system restore, but there there are no points beyond when i started the updates on Sept. 28.

How do I get the device manager to show these ports, there are no ports listed at all.

Thanks in advance for your help.

I'm working on a Averatec 3260-EH1. First Averatec I've looked at. Little brother's friend brought it to me because the modem quit working. (They live in the country without any other option but dial-up.) They think it happened when they tried ot install an iPOD. His wife had already reinstalled Windows with no luck. However, I re-installed Windows XP Home also just to make sure I had a clean slate and I'm getting the same problem. I downloaded the driver from Averatec's site. When I install it & re-boot, it shows up briefly in DM, but still doesn't work & then it disappears again. While it is there, it states to be using Com 4. (I have not at any point had the New Hardware Wizard appear.) So, I started looking at different angles and noticed that no ports were listed in DM. I went through Add New Hardware and added Com port. It came up with an error about resources. It was using IRQ 3 which I believe is correct for Com 4, yes? There are no external devices plugged in. I wondered if the modem was just bad, but that wouldn't explain the missing ports. All input is much appreciated. Any ideas?

After the most recent Windows update, I noticed that the USB wireless keyboard and mouse I normally keep connected to this netbook would not work; literally an overnight change, as they worked normally the previous day. Checked in device manager, and there were two Code 39 error entries ("Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.") for each port. To attempt repair, I first tried Microsoft Support's suggestion: uninstall the drivers, then reinstall them - this led to the same result. Next, on assumption something in the update may have caused the problem, I uninstalled the "Cumulative Update" (did not uninstall "Windows Malicious Software Removal Tool" nor "Security Update for Adobe Flash Player"), then retried uninstalling/reinstalling the drivers. Again, no resolution.Does anyone have any other suggestions for resolving this issue?  Thank you!

Device Manager does not have COMMS or PORTS in it,
I cant see what connected USB devices are using which ports?
as Iam required to change a connected USB cables port to port 8...

ANY HELP ANY1

many thanks
 

A:PORTS / LPT COMMS missing from Device Manager..?

I would suggest rebooting your computer after shutting it down for 5 minutes. After rebooting check device manager again to see if the ports have re-appeared. If they have not then run add hardware and try to install them manually.

Do you have the recovery software for this computer?

You have two computers listed which one is affected?

I'm wondering if someone could help me.  I went to print something yesterday, and it just didn't do anything.  After looking into it some more, I've noticed that the printer is offline, but it will not allow me to get it back online.  Trying to go into the device manager, nothing comes up at all.  Right clicking on the printer properties shows no ports at all, and I am stuck in that window because it is telling me that I have to select at least one port.  I try to add lpt1, but it says it already exists - but it doesn't show up?

A:Cd/dvd rom not show in device manager or in computer

After checking Hp's website for drivers, I find that particular laptop only supports Windows Vista, XP and 2000. So that may be the problem right there.

You have a couple of options here, one is use the drivers for Vista - bit specific and install in compatibility mode. Another option is to find the product specs page for the make and model laptop and find what make cd/dvd drive they used and go directly to that manufacturers website for the driver.
