Nelson R 0 Posted August 21, 2019 Share Posted August 21, 2019 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: http://www.orangepi.org/orangepibbsen/forum.php?mod=viewthread&tid=471&page=1#pid3822 but the problem persists! please help me I have two boards with this problem!

maxlinux2000 6 Posted August 28, 2019 Share Posted August 28, 2019 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.
