I changed the snd_printdd to a KERN_ERR and split the line under 80
columns. There's some additional cleanup that could happen with the
header-bLength, csize checks slightly below where this patch hits
(one of the length checks is redundant, as is the !csize check), but
I'm not well versed in the local style and didn't want to break
anything. =)

You can find them here: http://git.kernel.org/?p=linux/kernel/git/gregkh/usbutils.git;a=summary Done and attached. Also, support for this protocol has been added to the Linux kernel last year.

The internal sound card on this machine works well (hw:0).

If it's useful information, I've also booted Windows XP under VirtualBox (Linux host OS) and was able to use Focusrite's mixer application, see activity in the meters with a microphone, and hear differences when changing levels in the headphone out/mic in/etc. I was not able to play audio or record using the 18i6 through XP, though. The device does work as expected when running XP as a host OS. Any ideas on how I could get the 18i6 working, or is this a lost cause without documentation from Focusrite? Thanks, Nicolai Try making the Focusrite the primary device. This worked for me under somewhat similar circumstances.
