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 off-list. -- Emmanuel Kasper System Administrator www.libera.cc Find, compare, buy Linux & FreeBSD compatible hardware
