That should work fine, but do you know what to set in the kernel to make it get past the checks?

That should work.

First of all I’m more of a hardware person, so my solutions tend to be hardware based J

 

That being said, here is my proposed solution:

 

In the attached schematic, you use the +5V from the USB input connector as a logic signal to turn on the FET.

Because FET’s are voltage controlled devices, it takes very little current to turn them on J

 

If you use a high current FET and a high current supply you could supply AMPS to the USB device JJJ

 

What do you guys think ??
