Hi Hui, > There is always an on-board usb bluetooth hci on the laptops, if > the bluetooth function doesn't work well like a bt headset can't work > with HSP/HFP mode, we often plug an external usb BT hci to verify if > that headset could work with the exteral BT hci or not, in this > situation, there will be 2 hcis (hci0 and hci1) in the system, and > so far, the gnome can't handle the hci1 well so we met lots of > problems when debugging with hci1 under gnome. > > After adding this new module parameter, we could ban the on-board > usb hci by putting btusb.ignore_id=idVendor,idProduct to the bootargs, > then the external usb hci will be hci0 and there is only one hci > in the system. We could easily debug with the external usb bluetooth > hci after this change. > > Signed-off-by: Hui Wang <hui.wang@xxxxxxxxxxxxx> > --- > drivers/bluetooth/btusb.c | 11 +++++++++++ > 1 file changed, 11 insertions(+) please use this instead. echo “vvvv pppp 0 08fd 0002" > /sys/bus/usb/drivers/foo/new_id Regards Marcel
