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. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg --- Reading git-diff-tree failed
