contoller. There is no sharing of USB bandwidth. Sorry - that was
badly worded before...

not a mere curiosity. Yesterday I brought up FC2 and
then, with much help from Steve Harris and Fernando, got a new Planet

my USB mouse and getting huge xruns. Since USB is shared with the sound
chip I think it's an example of what we ae talking about here.
Not quite. If you have a USB sound card it's a different ball game,
because you don't just have two separate devices sharing the interrupt,
you actually have them competing for USB bus bandwidth. Although it
should work if they are on different USB controllers. Unfortunately I
am not an expert on USB so I can't help much more.
