My computer doesn't recognize my cybook. It shows as "unknown device" in the device manager, I get a message "USB device not recognized. One of the USB devices attached to this computer has malfunctioned, and windows does not recognize it."

I have no access to folders, so I can't add or delete any files. With an SD card in it, it's still not recognized, nor is the card.

It's also not recognized by the mobipocket desktop. It just keeps telling me to plug in the new device, as if I hadn't already done so. (I wouldn't expect it to be recognized when the computer itself doesn't recognize it.)

It's connected, it has charged from this usb hub. I use the hub often and I know it works. It's on 100% charged. I've tried updating drivers of everything under usb in the device manager. I've tried uninstalling the usb controllers, rebooting, and reinstalling (suggested on the microsoft website for "unknown device" issues). I've tried having the cybook connected and turned on when I boot the computer, and I've tried hooking it up with the computer already running. I downloaded a bunch of updates from windows update, including .net framework 3, hoping some update was needed that I didn't have. I have searched the Dell and Microsoft websites for "cybook" and found nothing. Of course Bookeen's site has nothing, nor does their owner's manual. I don't know what else to try.

More things tried:
----------------------------------
It also shows up as "unknown device" when signed in as administrator in safe mode.

I also tried using a different usb hub (the one the mouse is attached to so I know it works) and that made no difference.

I also tried the troubleshooter connected to the unknown device entry in the device manager, it didn't help.
----------------------------------

I wrote to Bookeen but don't expect to get a reply before at least tomorrow.

I've got windows xp, home edition. Version 2002. SP 2.

Obviously, if anyone has any idea how to fix this, I'd be very appreciative.
