Bluetooth: btusb: Ignore unknown Intel devices with generic descriptor
The Intel Bluetooth devices use the generic USB device/interface class descriptors that are assigned to Bluetooth H:2 conforming transports. T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 2.01 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs= 1 However newer chips have a bootloader stage and require firmware to be loaded before they are functional. To avoid any confusion for the users, just ignore unknown Intel Bluetooth devices. All the released Intel Bluetooth devices have an entry in the device table identifying their setup and support requirements. The advantage here is that older kernel can be booted with newer devices without causing any disturbance.
