Kernel log flooded by message
logitech-djreceiver 0003:046D:C53A.000C: logi_dj_hidpp_event: invalid
device index:7
This happens when the mouse is idle.
And it started since I begin using the mouse pad with Power Play technology.


Kernel ver: 5.6 pre RC

Hello Mike,

Yes, the Powerplay mat exports a static HID++ 2.0 device with index 7
to configure the led on the mat. The current code expects devices to
have a maximum index of 6, which is the maximum index of pairable
devices. 

I already submitted a patch adding support for the Logitech G Powerplay
mat but it wasn't been upstreamed it. I will attach it in case you want
to try it.

Cheers,
Filipe Laíns

    HID: logitech-dj: add support for the static device in the Powerplay mat/receiver

    The Logitech G Powerplay has a lightspeed receiver with a static HID++
    device with ID 7 attached to it to. It is used to configure the led on
    the mat. For this reason I increased the max number of devices.

Thanks, I tested the patch for a day and "logitech-djreceiver"
messages was not appear anymore and no other regressions are noted.
Why this patch wasn't been upstreamed?

Also would be good if "logitech-djreceiver" provides information for
upower daemon as how did it happening with unifying receiver and my
previous mouse Logitech Zone Touch Mouse T400.

For example:

$ upower --dump

Currently, only sensors show the power charge level, but without
"upower" daemon user-friendly indication not available in DE.

Lack of time I guess.

The new devices only export the battery voltage. We will need to
calculate the charge level with the charging curve. I tried getting in
touch with the upower upstream to figure out exactly what is needed in
upower's side but without luck.
