Hello,
I am writing because you are listed as author of the hid-logitech-dj driver. I
recently bought a Logitech Anywhere 3SB mouse, and found Linux didn't
recognize it. Thinking it was a simple case of new IDs not recognized, I
quickly added them to the logitch HID++ drivers (patch attached), both for USB
with the new receiver and for the Bluetooth direct connection.
I have noticed however that the patch while causing them to be recognized and
interacted with as HID++ devices, it has a flaw. The scroll wheel events are
reported by the linux kernel as being in hires mode, while haven't actually
enabled it on the mouse. You can fix that using Solaar, but some piece is
missing to enable it correctly in the driver. Since this is no longer a
trivial fix. I wanted to reach out. Do you have any suggestions?
Best regards
Allan
