Ubuntu - USB Flash Drive doesn't respond.?

I have Ubuntu Intrepid 8.10 64 bit installed on a custom built computer. My 8gb A-DATA flash drive does not respond. I've never had a problem with it and I've restarted several times. In Vista Ultimate on the same computer the drive responds, so I know that the usb ports are working and I know the flash drive... show more I have Ubuntu Intrepid 8.10 64 bit installed on a custom built computer.

In Vista Ultimate on the same computer the drive responds, so I know that the usb ports are working and I know the flash drive works.

Also - in Ubuntu, I have a usb wireless adapter here in my desk. I plugged it in to the computer while booted in Ubuntu and I connected to my wireless network. So I know that Ubuntu recognizes my USB wireless device. It's just not recognizing that flash drive.

What can I do?
Update: PLEASE READ!!!

As I said above, this flash drive WORKS in Vista on this SAME computer. So please do not tell me the thing is dead. It is fully functional and works absolutely fine. I tested it.
