Still remains a bug, or perhaps a different bug.
As per an email exchange with clemens, I had got
this patch:
http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg35743.html>
I fetched the then-current linus 2.6.12 git kernel sha1:
59a49e38711a146dc0bef4837c825b5422335460
Patched in alsa 1.0.9b - which went in fairly cleanly, btw - patched
in the above patch, compiled for the x86_64, and with great hope,
plugged in the ua-1000 again. Nope, same crash on unplug, and it
doesn't appear to recognise the device properly... from
/var/llog/messages

Jun 24 18:07:46 localhost kernel: usb 1-4: new high speed USB device

* nothing else
Now, the dump of the panic on removal of the ua-1000 I haven't got -
it's a long kernel panic and this laptop lacks serial port to send it
out of. I will bring the ua-1000 into work and plug it into a machine
that is externally rebootable as well as visible on the net, also
running 2.6.12 released - but at the moment I plan to just return the
ua-1000 monday afternoon based on the hum problem.
On the other hand, getting devices to work is fun, so I've put a lsusb
at the end of this message...

Ha! I wonder how good edirol has been about releasing detailed
information on their devices... I'm emailing them....
As it was, after upgrading to the 2.6.12+alsa+patch git kernel I
discovered that my original 2 channel usb midi device wasn't working
anymore, either, though it was properly recognised

Not sure how to get it in 1.1 mode, but here's lsusb -v attached...
