Hello,

First of all, I did check/tried anything i could find on similar issues, for similar SBCs

 

Main issue:  only 2/4 USB ports are powered, but they don't recognize any device (keyboard, mouse, memory stick),  although, if i plug in an USB hub, it lights up.

I also tried an Android and and an Ubuntu LXDE, same problem.

What bothers me is that mouse and keyboard worked with the original Android that came pre-installed on the board.

 

Config: - Orange Pi plus 2E (the one with 4 USB ports)  +  heat sink + HDMI to VGA converter

Power source: I tried 4 so far,  currently using a PSU of 5.15 V and 4 Amps, through the DC input, jack barrel connector

FTDI converter with Putty , being the only way i can use the keyboard

 

Running:  "ARMBIAN 5.38 stable Ubuntu 16.04.3 LTS 3.4.113-sun8i"  from eMMC

I am quite new to Linux and SBCs,  but i hope there is something simple I am missing.

 

Can you please help with any ideas?

 

PS: If you need any other info/details i would be happy to provide.

Tank you!

Hello,

 

Does anyone have any idea that may help?

Thanks,

 

Do you have any powered USB gub laying around? Try with it. And try modern kernel.
