Sorry, haven't checked this thread in a while.
Anyway, I found a way to get Transit-USB working in Vista. The solution is quite dumb, actually. You have to slide the volume lever down, and then up, before any sound will come out. But even though it's working, the latency is absolutely terrible. I get better latency from my pc's inbuilt soundcards with ASIO4ALL drivers.
It's now in my cupboard.

Yes...USB are not the best solution for audio. for MIDI it's fine, but not for audio. And I agree with Nextis, Mac platform is always a preferred platform around the world in this industry. True enough that Windows user can argue back with whatever reason you've got. But sad to say that I uses both Mac and Windows and I have not encounter much issues with Mac as opposed to Windows.
