But today it hung:

I am also running 2.6.7-rc2-mm2.
Here are logs with usb debug & usb storage debug:
I plug the device in:

Jun 7 13:05:00 dsd CRON[9381]: (root) CMD (test -x /usr/sbin/run-crons && /usr/sbin/run-crons )
All is fine up to here. At this point, I can mount and copy files, etc, but I have not done so in this instance. I now unplugged it straight away, as shown below:

Jun 7 13:05:30 dsd usb-storage: usb_stor_stop_transport called
I traced the code path from when the final inquiry command was recieved and I found:
1. usb.c:usb_stor_control_thread calls us->proto_handler, which is set to point at protocol.c:usb_stor_transparent_scsi_command
2. usb_stor_transparent_scsi_command calls transport.c:usb_stor_invoke_transport
3. usb_stor_invoke_transport makes the following call:
down(&(us->pusb_dev->serialize));
And code execution freezes here.I don't have the knowledge to debug this further, but hopefully this will be useful to someone who does.
