Hi Dave,
yes this is a thing which occures on XP with my devices too. The only
way I got that fixed is by declaring the Midi part as vendor specific and
using my own driver for usbmidi. (my device is using usbaudio and
usbmidi functions)
BTW:
Win ME does not show this behavour and W2000 +W98 usbaudio.sys
does not support midi.
