[BUG] LE12 on Rpi5 - RTL8153-based USB3.0 to wired ethernet adapter doesn't come up across a boot

[rkershenbaum]

Describe the bug

RTL8153-based USB3.0 to wired ethernet adapter doesn't come up across a boot. It does not appear in Settings/LibreELEC/ Connections. Unplugging it and replugging it causes it to activate until the next reboot.

How to reproduce

Steps to reproduce the behavior:

1. Plug a RTL8153-based Ethernet adapter into a USB 3.0 port on Rpi5.
2. Check that it is active in the settings screen
3. Reboot the Rpi5
4. Check the settings screen and note that the eth1 interface is not there.
5. Unplug and replug the adapter.
6. Note that the eth1 interface now appears in the setting scren.

The problem does not exist in LE 11.0.6, but appears to have been introduced in LE 12.

I had a similar problem on rpi4 with a normal ubuntu. It turned out that the vendor implemented two usb modes for the RTL8153-based device:

1. Ethernet device (vid: 0bda, pid: 8153)
2. CD Rom drive (vid: 0bda, pid: 8152)

The CD rom mode is thought to be used for installing windows drivers and to avoid shipping an additional mini cd. [1]
If the adapter is plugged before boot, the cd rom mode is active and no network device driver will be loaded.

To fix that, you for example could apply a udev rule which simply ejects the cdrom and reloads the usb device as per [2]. That worked fine for me.

I'm not familiar with LibreELEC in detail, but I guess there is some way to add udev rules. If no experienced developer jumps in, I could also have a look into where to add it.

It would be helpful to see the output of
lsusb
with adapter plugged before boot (non-working) and adapter plugged after boot (working). Then we could find the correct usb pids for the udev rule.

Actually , it's the other way around --

After boot = non-working:

This is with the workaround described installed that's described here (udev rule):

https://io.24hoursmedia.com/tech-notes/help-my-rpi4-thinks-my-usb-ethernet-is-a-storage-device

Without that, the device does show in lsusb as RTL8151 instead of RTL8153. IIRC, with the udev rule installed, the device does come up across a boot -- but only on the Rpi4, and not on the Rpi5, running the same nightlies.

Is this still happening in LE13 nightlies. Note it is expected that RPi5 will be updated to 6.12 in the “near future” which is expected to be the LTS release of linux for 2024. So the testing will need to be done on that release too.

[rkershenbaum]

I just tried the latest (20241103) LE13 nightly and -- good news -- the problem is fixed. The connection is recognized across a boot.

If you post here when the 6.12 test is needed, I'll try it again then.

FYI, I also tried my AX88179-based Ugreen USB3.0 to Ethernet adapter -- and it's still not recognized.

Thanks for staying on top of this!

[heitbaum]

Now the LE13 nightly builds are running kernel 6.12 - so if you can test / ... - then we will know if this is resolved for the LE13. https://test.libreelec.tv/13.0/RPi/RPi5/ - Please use the latest (2024-12-09 or newer)

[rkershenbaum]

Unfortunately, the problem is back in the 2024-12-09 LE13 release. The RTL8153-based adapter is not activated across a boot. It does work when I unplug it from the USB3.0 port and plug it back in while the system is up.

FYI, the AX88179-based adapter is still not recognized at all

Hope this helps. Let me know if and when I can do more testing.
