With the Bluetooth stack thats in Jaguar, the init() function in IOBluetoothHCIController will fail (return false) if another HCI controller is already present. Even without that functionality, you can easily set up your driver so that it matches on the device/vendor ID of your second USB device and your driver should take precedence over ours since ours only matches on device class and subclass. - Eric On Thursday, August 1, 2002, at 04:32 PM, Dmitri Moukhine wrote: Hi guys, What would happen if I plug another Bluetooth USB adapter in machine running Apple Bluetooth Stack and D-Link adapter plugged in? If the second adapter has different device/vendor id would it be possible to load my home made USB HCI driver against it? I'd like to test my driver and it would be perfect if I could do it on one > machine.
