This feature request is for adding support for USB Medium as an interface in
IPMITool. AMI BMC (OEM feature) provides Virtual USB devices in the host as
part of its feature list. IPMITool can use this 'Virtual USB device' as a
medium for Inband communication with BMC.
Just like any other interface, use can just give 'ipmitool -I usb xxxx' to
communicate with the BMC via USB Interface.
