Hello Hans et al.

Starting from v6.7 release I get the following messages repeating in `dmesg` regularly:

```

I've got the following hardware:

* Bus 006 Device 004: ID 046d:c52b Logitech, Inc. Unifying Receiver
* Logitech MX Keys
* Logitech M510v2

With v6.6 I do not get those messages.

I think this is related to 680ee411a98e ("HID: logitech-hidpp: Fix connect event race").

My speculation is that some of the devices enter powersaving state after being idle for some time (5 mins?), and then wake up and reconnect once I touch either keyboard or mouse. I should highlight that everything works just fine, it is the flood of messages that worries me.

Is it expected?

Thank you.
