I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

Welcome to the Lenovo Community!

The ACPI\INT33A3 device is related to Intel's Smart Connect Technology driver. Although I was unable to find the driver on Lenovo's website for your model, Intel does offer a driver download at the link below, give that one a try......

Hi, all.

I recently installed the RC build 7100 (64-bit) onto a Lenovo Z61p laptop. Everything seems to be proceeding normally ... however, there is one thing that I do not understand ...

The Device Manager shows a device that is not recognized. It is a "Mass Storage Controller" and the location is "PCI bus 21, device 0, function 2" and no other meaningful information whatsoever.

Can someone help with any information about this? What is it and what driver should I use to enable it (or not)? Etc.,

Thanks!

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device. 
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

Note: Device manager lists appropriate bluetooth antennae.  Some items are still showing up ok, but many (some new, some previously paired) are listed as unknown now, so they are useless to me until this is resolved.  This is a fairly new Flex5 (bought at Microcenter about a month ago).I ran the Lenovo "Vantage" program to get the latest bluetooth drivers on board.Tried uninstalling BT driver and running manual install of intel and Qualcomm drivers.  Windows10 is not seeing the Intel ones, I think as when I try to change the driver to the intel ones I only see the the QualcommAtheros and the generic bluetooth drivers available.  I ran that installation a number of times, but havn't been able to try the Intel drivers yet.  I'm not sure if they will fix the problem, but would like to try them, unless someone here can point me at something else that may be the cause.  Thanks for any info!

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.
The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.
The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.
Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.
I've tried:
uninstalling the device and rebooting
installing the latest updated chipset drivers from the dell website
windows updates
pretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

Any other ideas?
Thanks

A:XPS 15 9550 Bluetooth stopped working (Unknown USB device - device descriptor request failed)

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.
After rebooting, BT and my mouse is now working again.
Something seems to be really flaky here, but hopefully this will help others with the same issue.

Intel Sideband Fabric Device Driver is a bridge tothe Intel Dynamic Platform and Thermal Framework. This package isprovided for supported notebook models that are running a supported operating system. File name: sp65474.exe I don't know if not having that driver installed is related to the black screen issue.

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

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.

Thanks.
 

A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

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. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???
My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

I've tried to remove the device and reboot - same thing. I've tried to update the driver and it says the best driver is already installed c:\windows\inf\usb.inf

The ref url was resolved by changing the order of connecting the cables.....I have tried ever combo I can.
Can someone please tell me how to point to the correct drivers ?

Thanks
Daniel

I have purchased E5-573G-389U few months back. Since then I am not able to connect any of my mobiles be it Motorola or Samsung to the laptop. Everytime it says 'Unknown USB device (device descriptor request failed) driver error'.  I have tried a lot of options in your discussion forum but nothing worked. I am just fed up with the problem. I will request you to provide the solution to the said problem at the earliest. It was really a bitter experience buying this laptop.

Hey
1.)So my mouse(Corsair Harpoon RGB) was recently just working fine until one night i unplugged it and put it into computer and on that computer it didnt work so i went back to my laptop to plug it in there, but it showed the same problem it didnt respond the logo didn't light up so i went to the device manager and it said *title. So how do i fix this is there something with my mouse is there something with my software?
Oh yea and on top of that i have 2 more issues that i jut can't solve by myself.

2.) Unknown USB-device(port reset failed)
3.)DVD Drive(optical drive) doesnt show up on the device manager but it sounds like it's working and it opens and closes.
4.)Front ports of my PC doesnt work if i plug an USB in it doesnt do anything (it does work perfectly in the back)

I don't know though if i should make more threads but they somewhat relate to each other,
that's why they are just in 1 thread. If you need to ask any question, need pictures , my specifications or anything else just ask me.
Thanks in advance!
Best regards Hao.

Fresh install of Windows 10 and the last driver I need to sort out is the above.

I believe it is my powered USB 3 hub to which I plug in my keyboard and mouse. Technically it is working but I don't like seeing yellow triangles on devices.

So are there any fixes?

A:Unknown USB Device (device descriptor request failed)

If it's a generic USB 2.0 Powered Hub then technically there's should be no drivers needed by Windows, if it's a USB 3.0 Hub then I'm unsure (since I don't own any USB 3.0 Hubs).

Might be a Windows bug, basically Windows can't find the description information to display the Hub's name in the Device Manager example: Generic USB Hub, Root Hub Device, etc....

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

Hello,  I seem to be having an issue with my Thinkpad T470p. I've had it for about a year and a few months ago, all the 3 USB ports stopped working and so did the integrated camera. It would work at times and then stop working. For the past 2 weeks, everything has completely failed. So far I've done the following: -I've reset the BIOS to default settings and still there is no change.-The USB ports are enabled in BIOS settings as well. -Fast startup is diabled-The autosuspend for USB devices has been disabled in the power settings as well-All drivers have been updated using the Lenovo System Updates-This is a fresh install of Windows 10 so there is no previous state that I can go back to. (It wasn't working when I was running Ubuntu either even with all the right drivers installed.)-Troubleshooting cannot seem to find a fix for the error either One weird thing though is that my WD Elemnts HDD works fine when plugged in to any of the USB ports but other than that nothing else works. Any and all help will be much appreciated. My warranty expired just before these issues started so I don't really think I can get it repaired by Lenovo services.

Greetings folks

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770
Motherboard: AsROCK H77 Pro4/MVP
Windows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10.
Here is what they look like:
http://prntscr.com/d6rm6k

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

Thank you

I have an external Bluray/DVD drive (ODP1201=S3-B) that works perfectly on Windows 7 but is not recognised by my new laptop which has Windows 8.1 64 bit. Can anybody explain why this is and what I do to get pass it, or is this a problem with Windows 8.1?

The device is listed in Win 7 as "hp bd rom bc 5501h", and the driver is 6.1.7601.17514

I have now tried various USB devices; I have connected a USB 2.0 External Hard Drive and a USB 2.0 Canon Camera both of which work OK, I have also connected a Seagate 1T external drive which is USB 3.0 an that was OK as well (the ports are all USB 3.0 on the laptop hence the reference to the which USB type)

The error message is as follows: "USB Device Not Recognised", When I go in to Device Manager I find two USB error listings, Unknown USB Devise (Device Descriptor Request failed) & Unknown USB Devise (Port Reset Failed)

I have been advised that this error can arise when a drive doesn't receive enough power from the system. The device does have two USB connectors, I have tried using both of them. The power cable going to the powered USB on the laptop and the data going to the adjacent USB (there are a pair of USB sockets on either side of the laptop, the right hand side having the only powered socket).

A:Unknown USB Device - A request for the USB device descript

I'm too of opinion that it's a power issue. Laptops are not known to have much power thru USB ports, not even some desktops for that matter. Possible solutions: If that laptop has USB3 port you can try it in there, it gives more power and is compatible with USB2. Another one is to ad external power to the drive. One of the USB connectors on the twin cable has only two connection tabs and is for extra power to device. That one can be connected to universal USB charger for phones etc. That's how I solved a problem with a HDD in external enclosure.
