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 ...
