A vSphere administrator is unable to vMotion a virtual machine between two hosts. An error
message indicates that the USB device is not accessible on the target host.
What is causing this issue?
A.
The USB device was not enabled for vMotion when it was added to the virtual machine.
B.
ESXi does not support vMotion with a USB device attached to the virtual machine.
C.
The VMkernel port for vMotion is not enabled for USB traffic.
D.
The virtual machine has the wrong USB controller installed.

There is an option:
If you do not plan to migrate a virtual machine with USB devices attached, deselect the Support vMotion option.
This action reduces migration complexity, which results in better performance and stability.

When you migrate a virtual machine with attached USB devices away from the host to which the devices are connected, the devices remain connected to the virtual machine.
For a successful migration, review the following conditions:
■ You must configure all USB passthrough devices connected to a virtual machine for vMotion. If one or more devices is not configured for vMotion, the migration cannot proceed. For troubleshooting details, see the vSphere Troubleshooting documentation.
■ When you migrate a virtual machine with attached USB devices away from the host to which the devices are connected, the devices remain connected to the virtual machine. However, if you suspend or power off the virtual machine, the USB devices are disconnected and cannot reconnect when the virtual machine is resumed. The device connections can be restored only if you move the virtual machine back to the host to which the devices are attached.
■ If you resume a suspended virtual machine that has a Linux guest operating system, the resume process might mount the USB devices at a different location on the file system.
■ If a host with attached USB devices resides in a DRS cluster with distributed power management (DPM) enabled, disable DPM for that host. Otherwise DPM might turn off the host with the attached device. This action disconnects the device from the virtual machine because the virtual machine migrated to another host.
■ Remote USB devices require that the hosts be able to communicate over the management network following migration with vMotion, so the source and destination management network IP address families must match. You cannot migrate a virtual machine from a host that is registered to vCenter Server with an IPv4 address to a host that is registered with an IPv6 address.

basically you cant migrate it because the usb was not ready for vmotion and since its attached to the object it becomes part of the object and it doesnt have the ability to vmotion now.
either take off the usb or configure the usb prior to the vmotion.
