Run Chkdsk F in Windows XP
1. Be aware that it is no longer necessary to run Chkdsk F from the DOS command line. You can still do it this way if you'd like (open the DOS command line and type 'chkdsk /f'), but Chkdsk is now integrated into Windows itself.
2. Run Windows XP normally, allowing it to load fully.

3. Access the 'My Computer' menu. You can do this by clicking the Start menu and clicking the 'My Computer' menu option. You can also double-click the 'My Computer' icon if you've enabled it on your desktop.
4. Right-click on the drive on which you wish to run the Chkdsk F command.
5. Click 'Properties' in the right-click context menu.

7. Click on the 'Check Now' button in the 'Error-checking' frame of the Tools tab.
8. Click in the 'Automatically fix file system errors' check box under the 'Check disk options' frame in the following window. This is the step which enables the '/f' command in Chkdsk.
9. Click 'Start' to begin the Chkdsk scan. If there are a lot of processes running in the background, or if Chkdsk determines that it should be run when you next restart your computer, it will suggest it. It is always advisable to run the Chkdsk from the restart in this case.
10. Set your system to safe mode with the '/SAFEBOOT' command from the MSCONFIG program. Click 'Start' and 'Run.' Type 'MSCONFIG' and enable the '/SAFEBOOT' option from the BOOT.INI tab if your anti-virus or anti-spyware software is conflicting with the Chkdsk process.

Next, type 'sfc/scannow' in the command box and press 'OK.' If the utility finds any missing or corrupted files, you may need to insert the Windows installation CD into your CD/DVD drive, so that the utility can replace the damaged or missing files.

Diagnose the Problem
1. Determine whether the problem is not due to a malfunction of the USB device itself, but rather of the computer itself. To do this, plug the USB device into another computer. If the device does not work, then the problem is most likely coming from the device itself. If the USB device does work, then you know the problem is coming from the computer, and you can use the steps below to fix it.
2. Check to see whether or not the USB is correctly configured for the peripheral device that you are using it for. This peripheral may be a digital camera, scanner, PSP or camcorder that you are trying to connect to the PC with via the USB. Use the product manual to check if the USB cable matches the speed of the device. This is important because USB 2.0 cables may not work with USB 1.1 configured devices and vice versa.

3. Double-check to see that the cable corresponds with the type of device. If not, you will need to connect the device with the proper USB cable.
4. Continue to Section #2 below if you still receive 'Error Code 10' even after switching cables.
