[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



	HID IR device will not response to any command send from host when it is finishing paring and tring to reset itself.
During this period of time, usb_cleaer_halt will be fail and if hid_start_in soon again, we has the possibility trap in infinite loop.
