Only 1 USB port working on Rock Pi 4A+

#1

Hi guys, I am having problems with 3 out of 4 of the USB ports. Only the USB3.0 OTG port works.

Plugging a USB hub, keyboard or mouse has no response. I am running Armbian 22.05.3 Jammy. This is a brand new Rock Pi 4A+

Any ideas what I can do to fix it?

lsusb when I plug my USB devices into the working port:

Edit: It has something to do with Armbian. When I use the Debian Buster image from Radxa, all four USB ports work.

It mostly like you installed the wrong images, you must installed the 4C images on the 4A+. Can you check your image download link?

Hi Jack, thank you for your reply.

I downloaded the version here:
https://www.armbian.com/rockpi4/

It says it is compatible with Rock Pi 4A/B/C.

Better get a Braille reader since then you might be able to decipher the Armbian download pages more properly: “Images below are for model C. For A (without wireless) can be downloaded here and for B here.”

Light grey on lighter grey in the middle of some graphics chaos is one of the more sophisticated ways to hide text :slight_smile:

Haha, OK this was what I was looking at :roll_eyes:.

I tried the Rock Pi 4A+ images and everything works perfectly. Thank you everyone! :grinning:
