I will do some testing of this and report back if it works all the time 
or if it has the same intermittend problems as my internal USB device.

Apparently many notebooks (atleast many toshiba's) have devices that can 
be plugged in and out via software. The USB BT dongle in my notebook is 
one of these.. There's a button on the side of the notebook that can be 
used to be sure that the device is off (like in an airplane).
I found a patch for linux/driver/acpi/toshiba_acpi.c on this site:

http://nicolas.bettenburg.free.fr/linux/#c4

I hade to fiddle alot with it to make it work with 2.4.22 (I guess he 
has not written it against a recent kernel). I came up with a patch that 
worked ok with 2.4.22, and to my surprice it worked fine with 2.6.0 too.

My guess is that the ACPI stuff has been backported into 2.4.22 and 
that's why it's almost the same.. I put the patch I use here so you can 
look if you want: ftp://zappa.cx/pub/echinacea/toshiba_bluetooth.patch
It currently doesn't apply cleanly on 2.6.0-test9 but not important 
stuff just comments doesn't apply.

I would be glad if this is the problem (though I think it's not since I 
guess it's only job is to logically insert the USB dongle).
I'm no programmer so I might have done a poor conversion so it won't 
hurt to check.

Will it help if I attach a session when it works to see if it's any 
different?
