Disable USB port after power problem in pluged USB device

Recommended Posts

I have Orange Pi Zero and  plugged bad USB modem  with power problems.
Some moment modem  have power problem and disconnect from board.
USB port in Orange PI disabled after it - lsusb show one of two board's USB hub is absent

After reinstall image in this board, USB hub works well.

 

I think, USB hub disabled by OS when  USB port has errors.

Let me now. how to enabled USB hub without OS reinstall?

normally it should be enough to power off, wait some minutes and power on again..... should be a self-fixing fuse on the usb-port like on the Raspberry Pi
