If the device IDs can be changed when the firmware is loaded, then simply provide a driver that binds to the original IDs and uploads the firmware. The original IDs can be blacklisted from btusb so it won't interfere. The device will then boot the firmware, detach and reattach with new IDs - btusb will then bind. Repeat for every cold reset. If you can't change the IDs from firmware then an alternative would be to blacklist it from btusb and provide a userspace application triggered by a udev rule. Have it load the firmware and then poke /sys/bus/usb/drivers/btusb/new_id . -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
