I use a bluetooth software that establishes connections with my
phone via libbluetooth.so.1. Sometimes this software has to be
killed. When I do this, it leaves the bluetooth stack in a broken
state:
# hcitool scan
Scanning ...
Inquiry failed: Connection timed out
How can I prevent this? What is the best way to rectify the
situation? So far, only reloading the hci_usb kernel module (I use
a dongle) and reconfiguring hci0 works. Since some of my machines
have monolithic kernels, this requires a restart. I'd prefer if
there was a different solution.
Thanks for any advice.

Yeah, that fixed it. I guess I will now go and read up on why that
would make a difference.

Not needed anymore, and I prefer if I don't have to set it
explicitly.

Probably not: it's an El Cheapo dongle from around the corner, an
"Abo UB20". lsusb -vvv output attached.
It works just fine...

make sure that you activate the rswitch for the link policy. You can
also try to load hci_usb with reset=1 if available.
What kind of dongle is this? Is it already in my list?

the shouldn't be any problems, but anyway what kernel version is this
and what does hciconfig show after you discover this problem. Are there
any other information in dmesg or the logfiles?
