Orange Pi 2G-IoT - Ubuntu Server Image - Can not get USB port to work - Overlay?

ajktek · Published in 2018-5-17 00:12:02

Hello,

I am working with a Orange Pi 2G-IoT with the latest Ubuntu Server Image from orangepi.com. I have gotten pretty far with this device other then one issue, which is the USB port. I have not been able to get it to work properly in this Ubuntu image. I have tried multiple DIP configurations with no luck. I want to use it as a standard USB Host for plugging in a printer (USB A to B cable standard). I have read tutorials and I have seen issues posted about armbian and using overlays on other OPIs like the Zero, but nothing specific to the IOT-2g, and everything I have tried from the tutorials on other models have not worked to get the USB enabled so I wanted to ask the community here. How can I use this USB port? I do not need OTG and I only need to use the 1 port in normal host mode on Ubuntu.

Any suggestions on what I should try or what I need to do are appreciated. Thank you!

Here is some info from the image and what I am seeing in case it helps:

Has anyone been able to get the USB port to work on the Ubuntu image? I can not see any way to make it function, and I would like to verify it is possible at this point.

Any suggestions are appreciated again.

Thank you

Hi,
I have issue with USB port too. I want to use it for USB webcam but it does not detect the camera.
I even tested it with plugging a USB mouse but nothing happens in lsusb and it is always like this:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I changed toggle switches on the board and now it detects my cam
change it to 1,2,3,4 OFF 5,6,7,8 ON

Farid,

Thanks for the report! I hope you can clairify something for me.

Can you tell me which OS image you are using and how you are powering?

Are you on Ubuntu, Armbian, or Andoird?

Are you using the USB Micro for power or a batter direct?

Thanks!

Not getting much further.... has no one got the USB host mode to work with Ubuntu that can explain the setup?

I have now switch fully to battery power so the Micro USB is not used at all.

I did get a bit of additional output in my dmesg | grep USB at the end...

DIPs are 1-4 Down / 5-8 UP - with the opposite it does not boot from the card.

Anyone have any suggestions for me?

The idiots in orange pi did not use OTG usb port for power, instead they, for some idiotic reason, use coaxial plug for power, if you don't have the coaxial plug, you can use the GPIO pin 2 or 4 (positive) and pin 6
( negative). Be careful not to reverse them. I accidentally reversed them and the orange pi died in a puff of smoke!

Nope - I can't agree to your opimion:
I use microUSB (like used for Android phones) cable to power my OrPi 2G IoT and it worked fine. Important is to have enough power on the cable, so plug it directly into a laptop or power-suply with more than 2A. And don't use thin & long cable - use shorter and massive cable to get the power to the plug :-)
Another possibility is to solder 2 wires to the VBAT+ and VBAT- pins and feed it with 3,7V or a Lithium-Battery
