Bc2000 (for the BCF2000 & BCR2000)

I've got a "similar" problem with my newly purchased BCR2000, which
I'm using under Windows 2000 with Ableton Live.
I've installed the USB drivers (v1.1.1.1) and updated the BCR2000's
firmware. No problem there, as the PC recognizes the BCR2000
instantly, as does Ableton Live but there is no midi date being sent
from the BCR2000 to Ableton Live. However, if I disconnect the USB
lead and connect the BCR2000 via midi there is no problem, Ableton
Live receives midi data and I can control stuff with no problem.
It's just that I would much prefer to use the USB connection rather
than having loads of midi leads connected up.
I've also tried the version 1.2 USB drivers to no avail, basically
it's a rather infuriating glitch that I would like to get sorted out.
Anyone out there with answers to this problem?
