Subject: [PATCH] HID: logitech-dj: Fix forwarding of very long HID++ reports
|
|
|
|
The HID++ spec also defines very long HID++ reports, with a reportid of
|
|
0x12. The MX5000 and MX5500 keyboards use 0x12 output reports for sending
|
|
messages to display on their buildin LCD.
|
|
|
|
Userspace (libmx5000) supports this, in order for this to work when talking
|
|
to the HID devices instantiated for the keyboard by hid-logitech-dj,
|
|
we need to properly forward these reports to the device.
|
|
|
|
This commit fixes logi_dj_ll_raw_request not forwarding these reports.
|
|
|
|
Fixes: f2113c3020ef ("HID: logitech-dj: add support for Logitech Bluetooth Mini-Receiver")
