Yeah, and it interfered with my sound card (es1371) with the non-Creative
codec.  When I swap my audio card with my girl friend's card which is also
an es1371, but uses a different codec, the audio card worked fine.  It was
also NOT sharing an IRQ.

Makes me wonder how the kfir cards were built.  Perhaps their PCI hardware
isn't so great...  I tried *two* kfir card, and both acted the same way.

Hm.  For some reason it didn't help.  If I load it with loaded=1 after the
USB modules are loaded, it still locks up.  *very* odd.
