No, we don't support randomly toggling power for devices without their
cooperation - it's not generally going to end well. The reason it's
difficult to do this is that it's a bad idea.
I do understand the rationale. No issues with this.
Perhaps this is something
that could be implemented generically for USB as it's a hotpluggable bus
In this case we use VBUS as a power supply voltage. The problem with
regulator API used in this case is that we enable it on boot-up, but
then we cannot "symulate hotplug" anymore.
but I'm not convinced.
Maybe, I can look into USB driver and see if the VBUS is manageable from
there (so I could add some sysfs entry to control it if needed).
