New USB keyboard works on XP and Linux but not on W7

Got this keyboard.

It is just the right size, the feel of the keys is just right. It works on the PI (what I bought it for) and on XP but not on W7. W7 says it can't find the driver. I'd like to occasionally use it on W7. How do I find out what W7 doesn't like?

There is nothing in the eventvwr under hardware events.

The only driver windows 7 should need is the driver for the usb chipset. Anything else should be supplied by plugging in the device. Does it say it is USB certified? Windows 7 Compliant?

Doesn't have any of those tags so I guess it is not USB certified or W7 compliant. Oh well, never mind.
