mysterious disappearance of usb

Hi fellas

 I have a WinME/Linux Toshiba laptop with built in USB support and 2 usb ports. The other night I was playing around with the following pocketpc, a printer, a usb mass storage device and an non-powered 1->2 hub. At some stage, I`m not aware what the circumstances were exactly, USB just stopped working. I didn`t do anything physically violent with the cables. It wouldnt detect any plugged in devices under linux, and under windows, the USB controller appeared as disabled in the devices menu. When I tried to reenable it, it said device is not working or disconnected.

 I have never had any trouble with USB on this machine in the past, either on linux or windows.

 I guess this is a hardware failure, but I very much hope that it isn`t. Please tell me if there`s anything I can do short of sending the computer in for repairs.

 Also, if it sounds like I did something unsafe with
the combination of devices/hubs I was using, please tell me so that I know not to repeat it. I had been under the impression that USB was pretty foolproof but hey, I`m probably more of a fool than most..

Thanks

Check BIOS settings to ensure USB support is enabled, remove both devices(root hub and controller) from Device Manager, reboot, if the system is undamaged, Windows should detect and install the correct drivers for the root hub and controller. T

I dont know what happened but it works now. Thanks for the great advice. I'm really pleased since rather a lot depended on my having USB capability.
