Bug Description
It seems that an image dump from a USB device and passing through the actual device are treated differently by KVM. For instance, if I pass through a physical USB thumb drive I can select it from the virtual machine's boot menu. However, if I take an image dump of the very same thumb drive and then add it to the VM as a USB storage device, it does not appear as an option from the virtual machine's boot menu.
I would expect for the two to be functionally identical.

Thanks for reporting this bug.
Can you show
1. the url for the usb image you created (or the iso assuming you used usb-creator-gtk)
2. the exact command you used to create the usb stick dump
3. the exact kvm command line which you used in both cases
I'll try to reproduce.
