Paul,

Yes, the computer that shows this behaviour is a brand new Thinkpad with
SP2, automatic updates activated, so I assume I have the latest patches
of about everything. All older machines, even my Mac running OS X, cooperate
perfectly with my device.

Tried a lot to fix this in the meantime, but without any succes, so any help
on this is greatly appreciated.

Thanks,
Stefan

Did you check to see if all of the machines were running service pack 2?

Subject: [wdmaudiodev] USB MIDI device port won't show up some computers

Hello,

I am developing a Class compliant USB MIDI Device so that I can avoid
having to write a driver. Everything works fine, device installs
properly
on all XP equipped machines, but on a few computers, the MIDI Ports do
not show up in the applications. Tried to compare driver versions,
compared
registry entries without success.

Any idea how I could debug this?

Thanks,
Stefan
