Hello Marcel et al,
I get a kernel Oops with 2.6.5-mh3 (with and without preempt) and an
Acer BT-700 USB dongle on a Vaio Notebook, not when unplugging it, but
when plugging it back in.

Anything I can do?

Hi,
For the problem that the usb dongle doesn't work anymore with 2.6.6-rc1, After
some times I've found the patch that caused the problem and Alan Stern,
yesterday, sent me a patch that made it work.
The path is here:
http://marc.theaimsgroup.com/?l=linux-usb-devel&m=108214198732679&w=2
I hope this can help.
Bye!

for me it looks like that the hci_usb driver hits some bugs in the
current USB subsystem, but Alan Stern is going to fix them all. Please
work with him to fix them. If we need to change something on our side,
he will send me a patch and I'll include it.

Do this also work for 2.6.6-rcX?

The problem was already submitted to lkml (i found at least 3reports)
and one time declared impossible by Andrew Morton. I can't reproduce
this error with 2.6.6-rc1 because, the usb dongle ain't even working
at all. It seems USB is a bit messed up in that release.
In 2.6.5 there is an easy workaround. If you don't need the hci_usb
SCO (CONFIG_BT_HCIUSB_SCO) support, disable it in your kernelconfig.

check the latest 2.6.6-rc or Bitkeeper snapshots, because there are many
USB patches that are not merged into 2.6.5. If it still fails send a
report the USB mailing list, because I don't think that this is our
fault.
