I'm having an issue when trying to add an external USB hard disk to my Virt-Manager. I'm trying some new stuff in a Debian environment inside Virt-Manager.
These are the steps I take.
On VM settings I set USBController to USB3.0

Then, click on "Add hardware" button

Then, I choose "USB Host Device" and click on my "Western Digital" external USB drive and "Finish".

The hardware is added and visible:

When I try to run my VM I get this error:

This drive is not mounted in my laptop (host) so it's not being used (I guess).
'lsusb' shows the drive there and it's ok.
Anyone knows what is wrong?
