Then I will label M-audio devices "friendly".

Sorry I dropped a part of the name.
The vendor name is Terratec AUREON 5.1 USB MKII.

From what I have seen the Hercules Muse Pocket LT and the Ion TTUSB usb
turnable both work "as is".
I think I'm going to label "friendly" standard usb sound devices which
work "as is" without requiring an entry in usbquirks.h
(which does not mean the opposite will mean automatically "unfriendly" )
Thanks for these informations and also for people who replied to me
Find, compare, buy Linux & FreeBSD compatible hardware
