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.

Benjamin, is there any updates on this? Were you able to test it?
Thank you,

I guess we can't do anything else than to trust Logitech that they will
not assign conflicting device_index ID in the future to something that
will not be HID++, right?
Or is this properly documented somewhere?

Yes, we need to trust Logitech on this. There's isn't anything
documented regarding this AFAIK.
Even if Logitech released a device with index 7 that didn't support
HID++, it wouldn't be that big of an issue. We would just end up with a
hidraw node which would export a vendor page report descriptor but the
device wouldn't actually reply to anything.

Given the silence from Nestor, I guess we can just apply this for 5.7;
pushing to for-5.7/logitech branch.
