We should likely just remove c52f from the list of supported devices.
C52f receivers seem to have a different firmware as they are meant to
work with different devices than C534. So I guess it is safer to not
handle those right now and get the code in when it is ready.
Ack. Can you prepare a patch to drop the c52f id?
Yes. I have an other revert never submitted that I need to push, so I
guess I can do a revert session today.
I think I'll also buy one device with hopefully the C52F receiver as
the report descriptors attached in
https://bugzilla.kernel.org/show_bug.cgi?id=203619 seems different to
what I would have expected.
They are actually what I expected :)
The first USB interface is a mouse boot class device, since this is a mouse
only receiver. This means that the mouse report is unnumbered and we need to
extend the unnumbered mouse-report handling to handle this case. Also the
device is using the same highres mouse-reports as the gaming receiver is.
I'm actually preparing a patch right now which should fix this. Still might
be better to do the revert for 5.2 and get proper support for the c52f
receiver into 5.3.
