running windows XP student 2002 service pack 3. Keep getting the error message that a usb device is not functioning and windows does not recognize it. Nothing is plugged in. The device driver information says there are no drivers installed for the unknown device which is not plugged in. The device is not always listed in device drivers.. Nothing is plugged in to a usb port except our epson printer which is recognized in control panel and is functioning properly. I have looked on google and get a wide variety of links but no solution. any help would be appreciated. greymuzzle

Is this a laptop, or a fancy computer with sd card slots built into it and all?
Did you reinstall windows recently?
And last question, what is the exact make and model of the system?

greymuzzle hi. Look in Device Manager, for an exclamation, or question mark.
It could be an internal USB device.

greymuzzle, hi.
Please give us a rundown on your system, that would help, make and model (both machine and printer)

disconnect the printer, reboot. what happens now?

If ok, reconnect the printer and let windows install the printer and the card slot drivers. (Does the printer have SD card reader?)

to vistamike, LH,& Paulus88. My system is a tower computer name on tower is Enpower,definitely not a laptop, running windowsxp home ed,servpk3 AMD Althon(tm) 64 processor,3400+ 2.21ghz,2.43gb ram,phyextaddress hard drive 74.5 gb, 55.3 free space. I have disconnected printer rebooted still get error usb unknown device not recognized. There is nothing plugged into a usb port at this time. I can watch the device manager and see the unknown device appear and reappear. I disabled it and rebooted still comes back just as disabled. When I plug printer back in it is recognized in device manager and works fine. So I get the error even when there is nothing in a usb port. Windows is fully updated as far as I know(still learning about computers) and has not been recently installed. Hope this helps.

As has been mentioned, it could be an internal USB connection. Most likely a card reader.

I am not familiar enough with these internal usb connections to know what a next step would be. The printer in question is a Epson c88 pretty old by electronics standards. There is an sd card reader on the front of the computer. Not sure where you are trying to get me to go with your suggestions.Are you saying there are some device drivers that need updating?

You need to look in Device Manager.

Hi LH, When I look in device manager i find the unknown device and it says there are no drivers for this device. What are recommendations about dealing with this unknown device?

Try letting it do an online search for the driver,
And use this app (the free version) to let us know what your card reader is,

The old man is slow on the uptake sometimes. The costly version says 9 drivers are out of date. I will go back and pay better attention when I get to the site Thanks Grey muzzle

LH I uninstalled the wrong program went to the site you suggested downloaded the Sim free version which installed SIW and uniblue. Uniblue says there are 14 ancient drivers. I have recorded all the information pertaining to USB.PCI to HOST CONTROLLER new version 2.04.0001.0 USB ROOT HUB new version 4.90.3000.2 USB MASS STORAGE DEVICE new version 6.0.6000.0070 USB TO IDE (unplugged) 5.00.2042.1 Microsoft was listed as the manufacturer for all these. I DO NOT KNOW HOW TO UTILIZE THIS INFORMATION.

greymuzzle.

You can download the drivers for the Realtek USB 2.0 card reader (mass storage driver) ver. 6.1.7600.30126_101027 here: http://www.realtek.com.tw/down.....Down=false

Choose the XP/Vista/7 driver.
Just Unzip and run "Setup.exe"

This should clear the "Unknown Device" in your Device Manager.

To LH and G41M.I have successfully installed the program that G41M suggested but I cannot see where it has updated any of the drivers. Remember you are dealing with a rookie. I saw no option to actually run the program and am unsure if it is a command line function or what. Greymuzzle

greymuzzle,

After you install the Realtek USB 2.0 driver setup, do the error message that a usb device is not functioning and windows does not recognize it error still persist? Do you still see an "unknown" device in Device Manager?

Yes I still see the unknown device in the device manager. I figured I did not do something right. I have looked at the driver details and it still shows no drivers for unknown device and the other devices still have the old versions in the details. The update wizard says the old versions are all that is available. I appreciate your efforts. I am learning a lot even though the problem is persisting. Greymuzzle

The other devices have their drivers installed and functioning properly but maybe not up-to-date. Our main concern here is the "unknown" device because it is the the one that triggers the error message. And I think it is your Realtek USB 2.0 card reader.

The setup program should have installed the drivers for your version of Windows automatically, for some reasons it did not. If you still have the (unzipped) folder for the Realtek USB 2.0,right click on the "unknown" device in your Device Manger and choose "update driver". in the update wizard, select no to connect to Windows update and click "Next". In the next window, choose "Install from a list or specific location" and click "Next". Uncheck search removable media but check "include this search location" click Browse and point to the location where you have unzipped the Realtek USB 2.0 files. Go to the "DriverBin_32bit folder" and click OK.

Hi G41M, I followed your instructions andwent to the DriverBin_32bit folder and clicked OK. The wizard searched and said that the present driver was the best version.Please bear in mind the device manager says there are not drivers in stalled for this device and the details say the version is 5.1.2600.0 and the device Id is USB\VID_0000&PID_0000\5&21302E94&0&8. My computer is starting to have problems and so I am having some one look at it tomorrow. I will let you know the outcome and thank you very much for your time and effort. Greymuzzle

greymuzzle,

In your device manager can you see a USB 2.0 card reader in the list of devices?

From SIW can you give us the motherboard manufacturer and model.

The manufacturer is gigabyte I-DNA series motherboardGA-K8N51GMF-9 optimized for AMD Athlon(tm) 64 processor3400+ . I had some self inflicted hardware problems to address and now the PC is back working normally except for the usb device not recognized. I saw nothing under device manager about a usb card reader. Thank you for your patience. Greymuzzle

Hello,

I had just the same problem on my Laptop, NO USB Ports worked !!. Via Device Manager I simply uninstalled there the USB Controllers and restarted the System again. On start, Windows recognized the hardware and installed the USB Controllers again. Once finished every port of the Laptop was working fine. ► I run Windows Vista in Dutch. I hope this tip help you also, success

The problem with my computer turned out to be a defective usb jack in the assembly on the front of my computer. I could barely see the defect after I removed it and used a magnifying glass to see down isnside it. I think the problem may have been caused by an inexpensive backup hard drive that somehow malfunctioned and maybe damaged one of the contacts in the usb jack. After I unhooked that assembly from the mother board the error message never reappeared. I replaced the assembly and it is plugged into the same place on the motherboard where the original had been.

Well that is great news.
Also shows how a USB port can be easily damaged. (seen a few in my time).

Thanks for reporting back with your resolve.
