Hi,

The left usb port suddenly stopped working.

Here is the output of lsusb -tv:

The USB device connected on the left does not appear. It appears however if it is connected on the right.

No new message appears with dmesg | tail when usb device is connected or disconnected on the left usb plug. However new message appears with dmesg | tail when usb device is connected or disconnected on the right usb plug.

No new message appears in sudo journalctl -f -u systemd-udevd when usb device is connected on the left usb plug. However, new message appears in sudo journalctl -f -u systemd-udevd when usb device is connected on the right usb plug. Right usb plug works, left usb plug don’t.

Is it a hardware or software issue? How to solve it?

You tagged with pinephone pro - there is only one usb - perhaps you mean pinebook-pro ?

oh! yes. pinebook pro.

I have two pinebooks pro, pbp1 and pbp2. pbp2 has a problem on the USB 3.0 Type A port.

on pbp1, 8 buses are detected:


$ lsusb -t

on pbp2 only 6:

After reboot, usb 3 works partially.

usb mouse works:

journalctl -f -u systemd-udevd
avril 30 15:39:38 manjaro-microSD mtp-probe[24021]: checking bus 7, device 4: "/sys/devices/platform/usb@fe900000/fe900000.usb/xhci-hcd.1.auto/usb7/7-1"

But not usb-stick:

The window for mounting usb keys opens and closes immediately with or without an error message:

the operation was canceled

Or

no object for d-bus interface

Meanwhile, udevd seems to be detecting and not detecting then redetecting the usb stick in a loop.

it seems to be the usb key that is the problem: another usb key is working fine on the usb plug. However, this key works correctly on pbp1. I will test it on another computer.

It’s probably a hardware problem, either in the usb key or in pbp2. The key works on other computers, and other keys work on pbp2 usb port 3.0. The solution is to use other usb keys on this usb port. :expressionless:
