I tried windows 98SE. It works for a 1Gb flash drive, but not
for a 2Gb one. Both drives work without the cable.
Neither work under winXP SP3.
Both work under ubuntu 8.04 and 9.10 and backtrack 2
Sorry, don't have any others to test. Not enough computers at
home ...

XP self corrupts the usb drivers from time to time just like everything else.

Go to the device manager, and delete everything under the usb category.
Then his refresh and they'll reinstall. Sometimes you have to do this
several times.

First, in your BIOS Setup see if you have USB2 support AND that it is
enabled.

For WinXP, open "Device Manager" and look under "Universal Serial Bus
controllers," see if you have USB2 or "Extended USB" drivers.

If NOT, go to your motherboard manufacturer's site and look for a USB
driver update. Download to your HD and install.

Most current USB devices (other than KB/Mouse) require USB2 support to
work. Note that your motherboard must have USB2 support for Windows
drivers.

By the way, another example why Linux is the better OS.
