Is there a way to find out how many buses there with things like
lsusb? Or being concrete again: Does this output mean, that I have two
busses, that should be able to provide the double bandwidth?
$ /usr/sbin/lsusb
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 002: ID 0547:1002 Anchor Chips, Inc.
Bus 001 Device 001: ID 0000:0000
This would be interesting as I might consider using some data
intensive devices on one bus while the other is taken by the
soundcard.
