Hi thanks

About the reset issue, I get some response from marcel about reset csr dongles
-------- Marcel said :
this is a clear NAK since you gonna break all old CSR based dongles.
Within the Bluetooth 1.0b and 1.1 specification there was an issues
with if HCI_Reset should only reset the Bluetooth internals or also
the transport. So issuing HCI_Reset on an old dongle will cause an USB
reset.

The solution is to find the build id when CSR produced correct
firmware and set the HCI_RESET quirk based on that. I meant to do this
for a long time, but so far never got around to inquiry the correct
build id where this got fixed.
--------

But I think it's hard to find that build id, so ...
