Here is what I did and the results:
Set of steps 1:
- Do
sudo journalctl -f | tee hub_drive.txt
- Connect the hub+drive to the usb-c port
Result:
Here is the relevant part of hub_drive.txt:

From the logs, my hub manufacturer is GenesysLogic. I searched genesys logic linux hub external hard drive and I have found a post[1] regarding a problem very similar to mine. In that post, the problem occurred on Arch Linux. They fixed it by adding usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX and update grub.cfg. I tried to do the same thing in Qubes, but I still cannot make it work.
Here is what I did and the result:
- Read usb-qubes doc and readapt the steps to my case
- Add
usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX in dom0:/etc/default/grub
- Run in dom0:
grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg since there is no grub.cfg in /boot/grub2
- Reboot
- Do
cat /sys/module/usbcore/parameters/autosuspend in dom0
Result:
I get -1 as planned
- Do
sudo qubesctl state.sls qvm.sys-usb
- Restart
sys-usb
- Do
cat /sys/module/usbcore/parameters/autosuspend in sys-usb
Result:
I get 2 instead of -1
- Do
sudo journalctl -f
- Insert the hub+drive
Result:
It shows the same output above (hub_drive.txt)
- Manually add
usbcore.autosuspend=-1 in grub.cfg in the template vm used by sys-usb
- Shutdown the template vm
- Restart
sys-usb
- Do
cat /sys/module/usbcore/parameters/autosuspend in sys-usb
Result:
I get 2 instead of -1
- Do
sudo journalctl -f
- Insert the hub+drive
Result:
It shows the same output above (hub_drive.txt)
- Unplug the hub
- Do
sudo sh -c 'echo "-1" > /sys/module/usbcore/parameters/autosuspend' in sys-usb
- Do
cat /sys/module/usbcore/parameters/autosuspend in sys-usb
Result:
I get -1 as expected
- Do
sudo journalctl -f
- Insert the hub+drive
Result:
It shows the same output above (hub_drive.txt). It didn’t work in the Arch Linux post[1] either.
- Clone
sys-usb to sys-usb-clone-1
- Shutdown
sys-usb
- Delete
sys-usb
- Do
sudo qubesctl state.sls qvm.sys-usb
- Start a fresh new
sys-usb
- Do
cat /sys/module/usbcore/parameters/autosuspend in sys-usb
Result:
I get 2 instead of -1
- Do
sudo journalctl -f
- Insert the hub+drive
Result:
It shows the same output above (hub_drive.txt)
Questions:
- Am I on the right track with the solution on the Arch Linux Forum[1]?
1.1. If yes, how do I set correctly usbcore.autosuspend=-1 in Qubes OS?
1.2. If no, what should I do to make the Qubes OS detect the drive through th hub?
