My sandisk usb flash drive does not show up as a drive in a Dell Optiplex GX280 w/ winXP pro. The same flash drive shows up in numerous other Dell, IBM and HP computers, just 'plug and play'. Same drivers show up on all the computers, 2 entries in device manager - one under disk drives and one under storage volumes\generic volumes. Everything appears to be exactly the same, everything working properly, except it doesn't show up in windows explorer as a removable drive or anything else. Doesn't matter which usb port I plug into, doesn't work. Other than a mouse, none of the usb ports are being used. Any ideas?
