Indeed.  USB 2.0 has 8000 subframes per second, but this doesn't
change things much.

The USB 2.0 spec says that 2.0 devices should work in 1.x mode, too.

The only 2.0 device tested so far is the Audigy 2 NX, and it doesn't
really work.  (It doesn't work in 1.x mode, either, so I think the 2.0
support in the driver isn't broken.)

Edirol devices usually work reliably with Linux.  However, the only
device with more than two inputs is the UA-1000, having ten inputs and
outputs, which may be more than you want.

AFAIK the Emagic EMI 6|2m works.
