It works great with 2.6.9-bk4, I have not tested it with 2.6.9-final but maybe it works, even if in -bk4 there are several usb patches.
Waiting for 2.6.10 !

Since I use 2.6.8.1 I have a lot of problems (and most people have) with usb subsystem. Usb keys, usb hd and usb dvd recorders don't work or cause kernel errors in scsi subsystem. I'm terribly disappointed because from 2.6.7, things get worst and worst. Is it so hard to create a stable scsi subsystem??
With 2.6.9-bk4, problems are bit less huge. When I unplug my usb dvd writer, that's isn't mounted at all, scsi subsystem and usb subsystem crash. That's the dmesg output:
Device sr0 not ready.

And then, when I plug in something, kernel doesn't respond. With 2.6.9-final, the problem is much more big:
