What version of kvm, or what was the commit HEAD hash?

What does the patch report as the method of access to the USB
file-system? The first time usb_host_scan() is called it reports its
attempts to find a suitable access method.

Does the same device work without the patch? The device is a
USB-to-serial converter? Is there a host process attached to it? ( USB
device raw access requires the host to release the device or you'll get
all kinds of problems and potential data corruption if it is a block
device).

The location of the error you report is outside the scope of the patch
itself. The patch is only responsible for determining the available
devices and listing them.

The issue you're experiencing could be related to the recent changes to
USB support introduced by Max.
