Hi Lei,

What’s your final purpose for this?

Now we already have KCS between host and bmc.

Thanks,

Kwin.

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?
