[arm-allstar] Power cycle USB

[Roger Coudé]

One of the mountain top repeater we have had a major ground fault after an ice storm.
Almost all equipement, including commercial and amateur was heavily damaged.
We replaced all equipement and added galvanic isolation in order to protect the RPI from possible ground fault from the radio.
A simple solution was to use usb isolators and it did the trick.
However, these components sometimes introduce a voltage ramp up and some sound cards are not recognized after reboot.
That was easily solved by using the usb power cycle in admin menu, since the dc-dc does not have ramp up when already powered.
Now that function has been removed and we have to wait next summer to go to the site and power cycle the sound card manually.
Is there a script or command we can use aside to get that usb power cycle back?
