You probably missed this, when I posted it, I guess, here:

	Here's an announcement for people interested in using USB devices
	with invalid configuration descriptors.  I've completed a series
	of patches that will make the system accept such devices, to the
	extent that it can.  You will have to apply all three patches in
	sequence; each is a prerequisite for the next.  They should go on
	top of a 2.6.4 system.  The patches are:
	
	as221:  http://marc.theaimsgroup.com/?l=linux-usb-devel&m=107937025411336&w=2
	as222:  http://marc.theaimsgroup.com/?l=linux-usb-devel&m=107937021027794&w=2
	as223:  http://marc.theaimsgroup.com/?l=linux-usb-devel&m=107937029404286&w=2
	
	The first two patches just improve the error logging; you might
	like to see what happens when you plug in your devices.  The third
	is the one that changes the kernel's behavior.  Please let me know
	if the patches don't work as expected.
	
	Not all the USB drivers will work properly with that third patch
	installed, so be warned.  The USB audio class driver should be
	okay.  I have no idea what will happen with the ALSA USB
	audio/MIDI driver; it hasn't been updated yet.

I couldn't test this yet - my Quattro is collecting dust somewhere and
is waiting for Ebay.

Ciao
