Possibly related to this:
I can’t comment in that thread since I’m not on the testing team, but I noticed that sys-usb no longer allows passthrough of inputs. On a fresh installation (updated) I tried editing
/etc/qubes-rpc/policy/qubes.InputKeyboard and its mouse counterpart as per the documentation but it didn’t work.
I tried the
sudo qubesctl state.sls qvm.usb-keyboard but it also didn’t work.
My USB input devices work fine even for LUKS until a sys-usb is started. (The fresh installation didn’t come with a sys-usb, by the way.) The input device notifications appear but the devices are unresponsive. Shutting down sys-usb doesn’t bring the devices back.
For reference I use a debian-11-minimal with only the following modifications:
The usb controller attached with no strict reset set to ‘true’
Kernelopts set to include ‘iommu=soft swiotlb=8192’.
Any input (pun totally intended) would be greatly appreciated.
