Hi Gerd,

I'm really sorry, but after rechecking my versions that worked (doing git
checkouts there) I don't get it working again :-(
I have no idea what's wrong now...

The startup issue is existing now again on all versions I tested - maybe
this was just a side effect during the bisect?

So finally - with the current master + your patch the assertion failed is
fixed but the startup issue seems to remain.

Any ideas how I could help you debugging this issue?
I tested it on Windows XP and a plain vanilla kernel 2.6.29.12 linux system
- both show the same behavior.

Attached the usb-filtered-dmesg from my guest linux booting up.
If you need further information, please let me know!
The usb 1-1 is my USB msd that gets not detected properly...

Thanks a lot!

Best regards,

Erik
