Need some help getting KB+M USB devices in dom0 (laptop)

[disp6252]

@10001110101

/etc/qubes-rpc/policy/qubes.InputMouse
I added the top line to allow the mouse.

usb dom0 allow,default_target=dom0
$anyvm $anyvm deny

Broken qrexec/policies after dom0 update (qvm-copy, clipboard, mouse passthrough... not working)

As it turns out the culprit was a policy I misconfigured for qubes.ConnectTCP. For those stumbling upon this, if you change a policy from ask to allow, you should remember to remove default_target= if present.
