There have been a lot recent postings about various USB devices. Assuming that I have indeed blacklisted the OSS driver and snd-usb-audio is registering, etc. It still will not work unless the new module uhic-hcd (instaead of usb-uhci) is loaded. However, this module will not unload correctly and can cause a hangup on shutdown. Get stuff like: URB-status -104 USB-request-URB -32 and hangs. Doing a rmmod (or modprobe -r) does not succede and anything dealing with modules is now parallized. lsmod, etc., are no longer accessible. NO usb until this business is cleared up, I am afraid. (If anyone has solved it, please let the rest of us know how!)
