then try it. I've even had particularly strange devices behave better
on a powered hub.
Connect your USB<>MIDI interface directly to your computer, not through
an external USB hub. I have an external USB soundcard; when connected
via my external 7-port hub, audio I/O skips in both directions.
Connecting directly fixed it.
It's already plugged directly into one of the laptop's usb ports.
I've
also tried using different ports, but that doesn't seem to make much
difference.
