I recently purchased an external keyboard and mouse with one of those
wireless USB dongles to connect to my Thinkpad when I work at my desk
with the external monitor.
In qubes.InputKeyboard I have defined the following:
sys-net dom0 ask,default_target=dom0
app-dev dom0 ask,default_target=dom0
$anyvm $anyvm deny
(qubes.InputMouse looks the same)
Just now I am using my Thinkpad in another place and there are no USB
devices attached (no dongle, nothing else). When I restarted all my
qubes I got the dom0 popup asking me whether I'd like to allow an action
from sys-net to dom0 refering to qubes.InputKeyboard policy.
I denied and my laptop keyboard (obviously) still works as it's not
connected via USB.
What was that? How can I find out what exactly get's detected as a
keyboard in sys-net that then would trigger this notification?
(My USB controller is either connected to sys-net or app-dev depending
on what I am doing at the moment).

Ok, via lsusb and searching for the respective devices I found a

qubes-users thread that ultimately lead me to this issue:
https://github.com/QubesOS/qubes-issues/issues/3604
Turns out my Acer integrated webcam is somehow recognized as a webcam.
So after adding:
ENV{ID_MODEL}=="*Camera", GOTO="qubes_input_proxy_end"
in /etc/udev/rules.d/90-qubes-input-proxy.rules as mentioned in the
github issue I no longer get the extra prompt.
