I have two usb keyboards, one no-name cheapo thing and an old logitech. When i plug them in to my computer they pop up in device manager as "Unknown device" respective "USB-receiver". Both of them fail to install any drivers, neighter automatically or through windows update.

Both keyboards work perfectly on another computer i have with vista 32bit.

Can this be one of those cases where a device does not work in 64bit version of windows? I doubt it though since I've never had that problem before with any device and i thought that basic things like keyboards would be kind of failsafe.

I don't really know how to start debugging this issue. I've tried all the obvious, rebooting, changing usb-port etc. Are there any generic x64 keyboard drivers you can use? Is there any way to find the manufacturer of the keyboard over usb? There is nothing written on it.
