Just got a keylab 61 today, loving it so far. My only gripe was that I couldn't get the Midi control center to read my device. I noticed that it was a pretty common problem in the forums, so I started getting worried.
Totally at random, I tried unplugging the keylab from my usb 3 port and plugged it into my usb 2 port. problem solved.
Windows 7 64 bit.
