The first thing to do was not uninstall the drivers - it was to reboot the system, Windows does that sometimes when it gets confused. It had nothing to do with your drivers, Windows had just stopped detecting changes in that device. If it WAS the drivers, (unlikely, as you made no changes to the system), you should have re-installed or repaired the drivers - not uninstalled them.

Since you now have no drivers, try re-installing the operating system, or try google-ing for the drivers themselves. Also, try the device installation wizard, which, after some exploration, should bear a USB device without any drivers. I suppose you should try this first, before even thinking about re-installing Windows.
