HID developers, Ever since this commit: 9d1bd9346241 HID: logitech-dj: Add support for a new lightspeed receiver iteration My Logitech G915 TKL keyboard does not work anymore. There is an error message in the kernel log: logitech-hidpp-device 0003:046D:408E.0004: hidpp_root_get_protocol_version: received protocol error 0x08 And the key mapping is broken (ex. pressing the 'F' key results in a '3'). The receiver I'm using has the USB PID 0xc547 which was added to a list of devices using the logitech-dh driver with that commit. So I believe it's using the logitech-dj driver instead of a generic hid driver from that point on. However, that causes my issues... I would humbly ask this commit to be reverted or the PID above be removed from the list while this issue can be investigated and resolved. Please let me know if I can provide any more information or help resolve this issue somehow. Thanks, Andre
