The eject was done on the guest but not on the client, right ?

> GSpice-CRITICAL **: usbredirhost: error resetting device:

The device is not plugged to the client machine anymore, so it's
expected a reset sent to it fails.

The reset is sent by usbredirhost when releasing the device:
 /* reset the device before re-binding the kernel drivers, so that the
    kernel drivers get the device in a clean state. */

Optionally, the code can check for this specific error-code
and not log an error in such a scenario.

To cleanly plug out the device:
1. On the guest - eject the usb device
2. File->Usb Devices menu - deselect the device
3. On the client -  eject the usb device
4. Plug out the device

yes.

These steps work well.

Thanks!
