Subject: USB problems encountered when offing Zaurus

---

I got this when I try to turn off Zaurus SL-5560.
Any idea what went wrong?

I am using 2.6.0-test2-mm2-kj1. I am trying to turn
off my Zaurus, and then turn it on again. When I turn
it off, I get the following messages. When I turn it
on, and try to do a samba mount, i get pretty unstable
connection.pretty unstable
connection.

Known bug, I have a fix for this in my tree which will get sent to Linus
in a few days. The patch for this was posted to the linux-usb-devel
mailing list last week if it's really bothering you :)
