I'll try reverting it when I have more time (which is probably end of
next week.. merge window).

All I get for a unplug/replug is

  usb 5-4.2.2: USB disconnect, device number 10
  usb 5-4.2.2: new full-speed USB device number 11 using xhci_hcd
  usb 5-4.2.2: New USB device found, idVendor=046d, idProduct=c52b,
bcdDevice=24.11
  usb 5-4.2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
  usb 5-4.2.2: Product: USB Receiver
  usb 5-4.2.2: Manufacturer: Logitech

and then

  logitech-djreceiver 0003:046D:C52B.0019: hiddev100,hidraw9: USB HID
v1.11 Device [Logitech USB Receiver] on usb-0000:46:00.1-4.2.2/input2
  input: Logitech MX Anywhere 3 as

  logitech-hidpp-device 0003:046D:4090.001A: input,hidraw10: USB HID
v1.11 Mouse [Logitech MX Anywhere 3] on
usb-0000:46:00.1-4.2.2/input2:1
  logitech-hidpp-device 0003:046D:4090.001A: HID++ 4.5 device connected.

but doing some grepping, at bootup time I also see a line line

  hid-generic 0003:046D:4090.000E: input,hidraw10: USB HID v1.11 Mouse
[Logitech Wireless Device PID:4090] on usb-0000:46:00.1-4.2.2/input2:1

which does not happen at replug. There's a few other boot-time
messages that seem to be about module init stuff too, ie

  input: Logitech USB Receiver as /devices/...
  input: Logitech USB Receiver Mouse as /devices/...
  input: Logitech USB Receiver Consumer Control as /devices/...
  input: Logitech USB Receiver System Control as /devices/...
  input: Logitech Wireless Device PID:4090 Mouse as /devices/...

and that only happens once and then never again. Some module loading
thing? I have

  CONFIG_HID=y
  CONFIG_HID_BATTERY_STRENGTH=y
  CONFIG_HIDRAW=y
  CONFIG_HID_GENERIC=y

but then the Logitech part is modules:

  CONFIG_HID_LOGITECH=m
  CONFIG_HID_LOGITECH_DJ=m
  CONFIG_HID_LOGITECH_HIDPP=m

which I think is all normal (ie I have my own local config, but that
part matches the default distro kernel config)
