Hey folks, I have a 6,1 Mac Pro and I just bought a Vortex Race II Mechanical Keyboard. It's pretty amazing and works fantastic in Windows, but on the OS X side it's very frustrating. They Keyboard is recognized and works with a U.S. standard keyboard profile and shows up in the system profiler under the USB tree. HOWEVER, after about 10 minutes (even if I'm in the middle of typing) it just stops working! The LED's stay lit, and it still appears in the system profiler, but you press a key and nothing! I know the original Apple USB keyboard has always had power issues, but after searching the web for quite some time I can't seem to find a fix. Just curious if anyone else out there using a USB keyboard has had similar issues.
