I am trying to hide usb controllers form dom0 and I had followed this doc USB qubes | Qubes OS
Note: I am using external keyboard
inputs :
sudo nano /etc/default/grub
outputs :
GRUB_CMDLINE_LINUX=“rd.luks.uuid=luks-fe66ed55-5286-486b-86e9-87f3b04d7cef rd.lvm.lv=qubes_dom0/root rd.lvm.lv=qubes_dom0/swap plymouth.ignore-serial>.<serial-consoles i915.alpha_support=1 rd.driver.pre=btrfs rhgb quiet” usbcore…authorized_default=0 rd.qubes.hide_all_usb
I have added to the previous line "usbcore.authorized_default=0 rd.qubes.hide_all_usb"
2- sudo grub2-mkconfig -o /boot/grub2/grub.cfg
outputs:
/etc/default/grub: line 6: usbcore.authorized_default=0: command not found
what is the problem here ?
