Hi Lei,

There is a script [usb-ctrl][1] hosted in intel-bmc.

It supports the VirtualMedia feature by insert/eject files to the host

as a USB mass-storage device.

Comparing to the existing [state_hook][2] in jsnbd, it supports

multiple UDCs, so it supports mount multiple files.



In addition, I have some updates on the usb-ctrl script to make it

support the USB ECM device, which creates a USB ethernet device

between BMC and the host.



So my proposal is to add the `usb-ctrl` script into the phosphor-misc

repo so that it gets reviewed and could be used by upstream.



Any ideas?
