USB not working, debounce issue on 6.12.56-current-meson64

[dabozz]

Hi,

I currently have the issue of a non working usb port on my odroidhc4. 

dmesg output:

[  133.464610] usb usb1-port2: connect-debounce failed

The port does not show up when lsusb is entered.

 

uname -a:

Linux odroidhc4 6.12.56-current-meson64 #1 SMP PREEMPT Wed Oct 29 13:09:02 UTC 2025 aarch64 GNU/Linux

 

I solved this temporairly a while ago by booting an older kernel (linux-image-6.12.43+deb12-arm64) like mentioned here: 

 

Are there any progresses on how to fix this reliably? Because I think still running kernel 6.6.63 is not save.

 

Thanks for your answer in advance, if you need more information I am happy to deliver.

6.6 is LTS kernel https://www.kernel.org/category/faq.html When some security issue is found, it goes into all LTS kernels. Higher version number does not guarantee bigger safety. Most recent has more functional bug fixes and new features and is generally more fragile - bugs / holes yet to be found.

Yes, v25.11.1 with 6.12.y https://www.armbian.com/odroid-hc4/ doesn't have those problems. At least I could not recreate them. Booting HC4, plugged in two usb devices, all good: https://paste.armbian.com/ibifozegof
