sys-usb fail to start

[holiman]

Qubes OS version:

4.0 (R4.0)

Affected TemplateVMs:

sys-usb

---

Steps to reproduce the behavior:

• Plug in some usb-thing, expect something to happen.
• Notice that the sys-usb is not running, try to start it with qvm-start sys-usb (or gui).
• Get the message PCI device <qubes.ext.pci.PCIDevice object at 0x72be4ade00f0> does not exist

Expected behavior:

• Plug in some usb-thing, something happens.

General notes:

Hardware Lenovo X1 Carbon Gen 5. USB devices have worked, but now they don't. Have only booted it a couple of times since it was installed, so I can't say how often it occurs yet.

Rebooted now, and then did systemctl status qubes-vm@sys-usb.service. It says basically the same thing, failed to start because of some pci-device that does not exist.

It was connected to a lenovo docking station over usb-c while I was installing it. I wonder if that docking station is the "missing" PCI device... if so, how do I make qubes forget about it?

Very likely. See qvm-pci ls sys-usb, and then use qvm-pci detach sys-usb <the device>

There are two devices there, one USB controller: Intel ... xHCI Controller and one Unknown device.

Definitely the "Unknown" one.

Thanks, detaching the Unknown device made sys-usb boot again!
