[awokd]

Qubes OS version:

R4.0rc4

Affected TemplateVMs:

---

Steps to reproduce the behavior:

Connect (non-block) USB device to a VM
Click on Eject in Device Widget to attempt to disconnect from VM

Expected behavior:

USB device detached from VM

Actual behavior:

USB device remains bold and attached to VM

General notes:

Target VM syslog/journalctl displays message similar to "Device attach failed: No device info received, connection failed, check backend side for details"

Related issues:

#3215

Attempting to use qvm-usb to attach results in the same "backend side failed" message.
Installing qubes-usb-proxy in sys-usb's template restored correct function to Device Widget's Eject. It already had qubes-input-proxy-sender.

Potential cause: Devices Widget not recognizing a failure message when used to connect a USB device

[awokd]

Same behavior noted when using widget to assign device to an AppVM that doesn't have qubes-usb-proxy installed. It gets "stuck" there and can't be unassigned with the widget. Physically removing the USB device works around it.

Found the cause - events in the backend were firing even if the device was not successfully attached/detached. @marmarek - that's one of yours.

I have the same problem when the VM where the USB device was attached is shutdown before detaching. It's not possible then to detach from command line or UX. Should I create another ticket for that?
