Unfortunately the ALSA and the manufacturer idea of standard compliant can
be different. The manufacturers seem to think that "We can make it run on
Windows" is equivalent to "standards compliant". Also for some they require
a firmware upload. So once the firmware is uploaded the card will run fine,
uploading the firmware can sometimes be a chore (it used to be on 2.4
kernels and early 2.6 that the usb bus drivers had a bug making it very
difficult to upload firmware, The bus would crash if it was reset. I think
this is now solved. But it indicates that "standards compliant" may not be
the whole story)
