    HID: yurex: recognize GeneralKeys wireless presenter as generic HID · 6dc1418e
    Tomoki Sekiyama authored
    Unfortunately, the device seems to have the same Vendor ID and Product ID
    as YUREX leg-shakes sensors, and the commit 6bc235a2 ("USB: add driver
    for Meywa-Denki & Kayac YUREX") added the ID to hid_ignore_list.
    
    I believe that we can distinguish YUREX and the Wireless Presenter by
    device type.  The patch below makes the driver ignore only YUREX
    (bInterfaceProtocol==0), and recognize Wireless Presenter
    (bInterfaceProtocol is keyboard or mouse) as generic HID.  (I don't have
    the Wireless Presenter, so not yet ested.)
