Hi, Our device (BT-1 wireless webcam) is not working correctly on 10.7.3. It works perfectly the first time after pairing, but on subsequent attempts to connect, openL2CAPChannelSync return kIOReturnNoDevice. The console gets errors like: [IOBluetoothDevice instantiateChannel] BluetoothHCIAuthenticationRequested failed because not connected and 2/29/12 10:33:49.000 AM kernel: [SendHCIRequestFormatted] ### ERROR: [0x080D] (Write Link Policy Settings) -- Send request failed (err = 0x0002 (kBluetoothHCIErrorNoConnection)) 2/29/12 10:34:04.000 AM kernel: [SendHCIRequestFormatted] ### ERROR: [0x041D] (Read Remote Version Information) -- Send request failed (err = 0x0002 (kBluetoothHCIErrorNoConnection)) 2/29/12 10:34:04.000 AM kernel: [SendHCIRequestFormatted] ### ERROR: [0x080D] (Write Link Policy Settings) -- Send request failed (err = 0x0002 (kBluetoothHCIErrorNoConnection)) 2/29/12 10:34:04.000 AM kernel: [SendHCIRequestFormatted] ### ERROR: [0x040B] (Link Key Request Reply) -- Send request failed (err = 0x0002 (kBluetoothHCIErrorNoConnection)) 2/29/12 10:34:16.000 AM kernel: [SendHCIRequestFormatted] ### ERROR: [0x080D] (Write Link Policy Settings) -- Send request failed (err = 0x0002 (kBluetoothHCIErrorNoConnection)) Removing the paired device and re-adding it makes it work again, just once that first time after pairing... Has anyone run into something like this with 10.7.3? Can someone from the Bluetooth team summarize the changes in 10.7.3 and make a guess as to what's gone wrong? Is our device doing something wrong during authentication? Many thanks, Ken _______________________________________________ Do not post admin requests to the list. They will be ignored.
