Hello to all, after plug a CDC device (Honeywell 1900 USB scanner), only one USB port on orange pi pc board works, I use 10 orange pi boards, the problem is only present int two of this boards. I notice that when I plug the CDC device alone the other ports not to work, but when I connect the CDC with another devices (mouse, keyboards) the problem is not present. I reinstall the img and the problem persists. The  two USB ports not to work anymore.

 

I think that is a hardware problem because the 5V in the two  USB ports are not present, and the plugged devices not to work!

 

I use Armbian_5.83_Orangepipc_Ubuntu_xenial_default_3.4.113_desktop.img 

 

Moreover I try the solution of loboris:

Same problem in a orangePi PC2... two usb ports death.

This occurs when I try to use a smartphone power supply in the microusb OTG port instead the regular power supply.

In this damaged orangepipc I'm using a hub usb3 with 4 extra ports. (5$ on ebay)

This is expected behaviour.
