How can I hard reset USB power? #211

Closed ic0xgkk closed 10 months ago

ic0xgkk commented 10 months ago

Hi,

I need to hard reset USB power to let my USB device restart. I noticed some x86_64 linux board can reset USB power by some ways, but it seems no way to reset arm board.

So, I have some questions,

  1. Why arm board can not reset USB power? It caused by USB controller difference or PCB design?
  2. How can I reset USB power in any ways in Linux? (not unbind and bind driver)

Thanks~

Lots of, especially cheap boards, simply pass through the 5V from input to the USB ports, so no kind of switches inbetween. Therefore "power cycle" is impossible."

For everything else: https://www.google.com/search?q=reset+usb+power+linux Last but not least this has nothing to do with armbian-config nor it is an issue of it.
