$50 XMR BOUNTY sys-net is controlling usbs no sys-usb, HELP how to create a sys-usb

Did you try the following:

  • Reboot the computer.
  • When the grub screen appears, press ‘e’
  • Use the up and down arrow keys to find the line beginning with
    module2 /vmlinuz
  • Go to the end of the line, using the left and right arrow keys. The line is quite long.
  • Add on a space, followed by qubes.skip_autostart
  • If you have some item to prevent USB devices from being seen by Dom0, then delete it. It may look like rd.qubes.hide_all_usb, but I am not sure if others exist.
  • Press F10, and login as usual. Normally your USB keyboard and mouse can be used.

None of the usual qubes will start. It should be possible to change the PCI devices attached to sys-net.

[Edited to add more details about navigating the grub entry]
