How to reset USB port

#1

I have a RockPi 4B

I noticed that following a reboot (cold or hot), sometimes the USB devices plugged into the USB port does not work any more. lsusb shows that no devices are connected to the port. To get it working I need to un-plug and re-plug the USB device, which always works after the system boots. But if I leave the device plugged in, even if I reboot many times, it may or may not connect.

I am using Debian 11, with https://radxa-repo.github.io/bsp/ compiled latest u-boot and stable linux headers.

I applied u-boot-latest_2023.10-1_arm64.deb and the linux stable .deb files.

Can anyone tell me why, and how can I reset the port / USB hub controller programmatically?

Can you tell me the hardware version the ROCK 4B you have? And please also tell me the image you use now.

#3

Hi, ROCK PI 4 v1.52, RK3399, the default Debian 10 OS does not boot on this version
(https://github.com/radxa-build/rock-pi-4b/releases/download/main-df04b3af/rockpi-4b-debian-buster-xfce4-arm64-20220401-0335-gpt.img.xz)
so I used default Debian 11 OS (https://github.com/radxa-build/rock-pi-4b/releases/download/20230427-1720/rock-pi-4b_debian_bullseye_kde_b30.img.xz), and noticed the same issue with and without the update to the u-boot.

#4

The linux 6.1 system for rock-4b is coming out soon, you can wait for this new release, or try the rock 4se 5.10 image: https://github.com/radxa-build/rock-4se/releases/download/b38/rock-4se_debian_bullseye_kde_b38.img.xz.

Ok I will try that tomorrow, can you tell me roughly when the 6.1 for rock-4b is coming?

#6

For 6.1, you can follow the merging of u-boot and kernel.

#7

Hi, I tried the rock 4se 5.10 image and it has the same issue. After the device boots, I can plug / remove / plug it many times and it always initializes properly. I suspect maybe the Depth Sensor takes too long to initialize at the beginning when the board is first powered. Is it possible to restart the USB interface / delay starting the USB interface until the system initializes for 20 seconds?

We observe similar behaviour on 4B+ with USB thermal cameras. Sometimes, randomly, when camera is disconnected and reconnected several times, the specific USB port dies and it does not recognize any new device until reboot. The other USB ports continue to work.

#9

We tried using a USB hub but it still doesn’t connect, again after it boots, we can plug / unplug as many times and it would connect, only if it is plugged in during boot that it doesn’t connect.

The device is unplugged and plugged in at ~180 seconds.
