Perhaps predictably after saying this, I find that using /boot/config-3.5.4-1.fc17.x86_64 as .config, then make localmodconfig and make menuconfig to turn off loads of network device drivers and such that would take hours to compile, usb audio is working on the sound.git kernel :-/ I quickly tested the VG-99 quirk (modified as per Clemens' suggestion) and that works too, so I'll work on generating a patch as per the instructions on alsa-project.org. If it's any use regarding the urb 0 -ENOSPACE error I was having, I can try and track down the config item difference that makes it work, or provide the config files for you to look at.. Please let me know if this would be useful. Should there be some dependency in the configs so that whatever item is making the difference is enabled by selecting SND_USB_AUDIO ? Thanks for the pointers :) Cheers, - Pete.
