Answers :

When an USB drive makes problem on one computer only then an updated mainboard/chipset driver may help.
\015\012If it doesn't help then it may be just incompatible with the computer's USB ports - that's not unusual. Therefore it's helpful to have an additional USB PCI card as alternative in the computer, best with NEC chip.
\015\012Cheap USB extension cables may cause problems too. The thinner and longer the higher the risk for problems. The plugs wear out in time.
\015\012USB ports on front of the computer are more problematic because the USB is leaded by a cable thru the computer case which is full of interferences. Furthermore the port a mechanically stressed, so the usually fail sooner or later.
\015\012Other attached USB devices may interfere, usually such ones that don't use a default Windows driver and which permanently transfer data, such as web cams.
\015\012Cheap USB hubs die slowly. First symptoms are disappearing devices and communication freezes.
\015\012If an USB device has been detected as 'unknown device' once it might be necessary to delete it in the device manager and replug it then.
\015\012Another try is a complete USB device clearing by Microsoft DEVCON and the RenewUSB.bat from http://www.robvanderwoude.com/devcon.html
\015\012A cleanup can be done manually too. Put the following two lines into Notepad and save them as DevManager.CMD:
\015\012set DEVMGR_SHOW_NONPRESENT_DEVICES=1
\015\012devmgmt.msc
\015\012Started thru this DevManager.CMD the Windows device manager shows non present devices too if you check "View" -> "Show hidden devices". Under "Disk drives", devices shown with a light gray icon are non present. Just delete them. Same procedure under "Storage volumes". There may be a lot of them...
\015\012My commandline tool DriveCleanup does it for all currently non present storage volumes and USB drives.
\015\012Microsoft has set up a page for General USB troubleshooting in Windows XP
\015\012To have DEVMGR_SHOW_NONPRESENT_DEVICES=1 set permanently, download and doubleclick this file: DevMgr_Show_1.reg. After next logon it takes effect.
It also sets DEVMGR_SHOW_DETAILS=1 to get the "Details" tab in the device's properies dialog under XP.
