Logitech keyboard and trackball not recognized in 64-bit Windows 7
I just built a Windows 7 desktop. Most things are working fine, but it doesn't recognize my Logitech keyboard (USB illuminated keyboard Y-UY95) and USB Trackman Wheel. These work fine on my old XP desktop and a friend's Win 7 64 bit laptop. They also seem alive when I boot into UEFI/BIOS, but once Windows starts, they're dead. Tech support thinks they ought to run just fine under HID. The last time I looked at Device Manager, trackman (no caps) was listed among the human interface devices, but was reported as lacking a driver. I can't find any drivers. I've tried all the USB ports. I'm not quite dead in the water, since I have an old PS/2 IBM keyboard and a Toshiba mouse that work. But I am very annoyed and any help will be greatly appreciated.
