[j-nsp] ability to turn USB port on/off for MX routing engine?

[Clarke Morledge]

This may seem like a totally random question, but does anyone know if 
there is a way to disable/enable power to the USB port that is built into 
the routing engine on the MX?

I have an application where it would be useful to flip the USB power on 
and off.   The USB device is not a hard disk so umount probably will not 
work.

This is NOT to be confused with the "request system power-off media usb" 
command that powers down the router and then forces the system to read the 
USB for the next boot image.

Thanks.
