[PATCH 3/6] HID: plantronics: Expose headset LEDs

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

 



hid-plantronics uses a custom input mapping, where unhandled usages get
ignored. Although these headsets have LEDs, they aren't handled in
plantronics_input_mapping, hence not exposed to the userspace. This
commit fixes it by adding a case for HID_UP_LED.

Tested with Plantronics Blackwire 3220 Series (047f:c056).
