Did a qubes-dom0-update + fedora template update last night. Reboot this morning and I can't reach the USB keyboard anymore.
I can't remember if I had removed my sys-usb VM after I got bitten recently and fixed the situation following this https://github.com/QubesOS/qubes-issues/issues/2270.
Following the explanation there I could boot and use the USB keyboard from my fedora on USB-key:
I did not have any entry with rd.qubes.hide_all_usb in xen-4.x.x.config
And I did not have a file /etc/systemd/system/multi-user.target.wants/qube...@sys-usb.service.
Any hint appreciated.
I am using Qubes as my home firewall and the entire house is disconnected (can't reconnect easily as I have VLans all over the place, dns server on QubesOS, etc...).
Had to edit out from grub.cfg rd.qubes.hide_all_usb entries to be able to enter the LUKS password
