contoller. There is no sharing of USB bandwidth. Sorry - that was
badly worded before...
Thanks for clarifying, I re-read your message and realized you might not
have a USB sound device. Anyway, if by "new Planet kernel" you mean 2.6
with the VP patches, then mouse activity should not be causing xruns.
I am not on the CCRMA list; if you have already posted your details then
send a link. This should be investigated further as it definitely
should work.
