You have to remember that USB devices indicate their bandwidth
requirements at enumeration. When playback starts, the device
requests that bandwidth; if not enough bandwidth is available at that
time, then the playback doesn't start. Likewise, if you're playing
back from a USB hard disk, that too will request bandwidth and get it
all or nothing.
So if you're trying to play back from your USB hard disk, and the
combined bandwidth requirements exceed what's available, the playback
probably won't even start. The clever solution, of course, is to not
connect your USB hard drive and your USB audio device to the same root
hub :)
Thanks Andy, this is good and useful information. :)
It makes me less scared of USB, but I still feel there's something
fishy hiding in that stuff. ;)
[Please bear with me being paranoid, I gotta deal with this problem
myself, I can't leave this up to others..]
Love,
Jens
