Subject: question on btusb_open()

Hi,

if this function is reentered there's a race with the error path. Can
it be reentered?

Regards
Oliver

Good. I can see no further obvious bugs in btusb. I am going on to do
power management for it.

no. The Bluetooth core will protect against it. The open callback will
be triggered by "hciconfig hci0 up" or hcid/bluetoothd.
