Hi Hans, > Commit 9834e586fa ("Bluetooth: btusb: Add workaround for Broadcom devices > without product id") was added to deal with the BT part of the BCM4356A2 > on GPD pocket laptops having an usb vid:pid of 0000:0000. > > After another commit to add support for the BCM UART connected BT ACPI-id > BCM2E7E used on the GPD win, it turns out that the BT on the GPD pocket is > connected via both USB and UART. Adding support for the BCM2E7E ACPI-id > causes it to switch to UART mode. > > The Windows shipped with the device is using it in UART mode and the > presence of the BCM2E7E ACPI-id combined with the 0 USB vid:pid also > indicates that the BT part was never meant to be used in USB mode. > > But not only is there no need to support the USB mode, supporting it > actually is troublesome, because with the workaround to support the all 0 > USB vid:pid, BT will just work for end users, until we add support for > the ACPI-id, after which users need to have userspace doing a btattach, > which may be considered a regression. > > To avoid this regression when switching things over to UART mode as > intended by the ACPI tables all along, this commit reverts the commit > adding the workaround to support the all 0 USB vid:pid. > > This reverts commit 9834e586fa ("Bluetooth: btusb: Add workaround for > Broadcom devices without product id"). > > Signed-off-by: Hans de Goede <hdegoede@xxxxxxxxxx> > --- > drivers/bluetooth/btusb.c | 18 ------------------ > 1 file changed, 18 deletions(-) can you send a series of patches, that first reverts this patch and then a patch adds the BCM2E7E id to the hci_bcm driver so that it will start working again.
