Error Message When You Try to Migrate Virtual Machine with USB
Devices Attached
Migration with vMotion cannot proceed and issues a confusing error message when you connect multiple
USB devices from an ESXi host to a virtual machine and one or more devices are not enabled for
vMotion.
Problem
The Migrate Virtual Machine wizard runs a compatibility check before a migration operation begins. If
unsupported USB devices are detected, the compatibility check fails and an error message similar to the
following appears: Currently connected device 'USB 1' uses backing 'path:1/7/1', which
is not accessible.
Cause
To successfully pass vMotion compatibility checks, you must enable all USB devices that are connected
to the virtual machine from a host for vMotion. If one or more devices are not enabled for vMotion,
migration will fail.
Solution
1 Make sure that the devices are not in the process of transferring data before removing them.
