Detailed reproduction steps

I've installed Batocera extracting the img and flashing it into an SSD connected to mi mini PC via USB to SATA adapter.

I've plugged the Wii U adapter into the USB port and was able to use it.
I rebooted Batocera and the adapter was not recognized.
Unplug the adapter from USB and plug it again (same port) let it to be recognized and work again.

Details of any attempts to fix this yourself

In the version 39 I wrote a script (custom.sh) that execute udevadm trigger afer ES loading, because this seems to solve the issue.
In version 40 this is not working anymore.
udevadm is just restarting ES, but the adapter is still not recognized.
After reboot lsusb is showing the adapter, but evtest is not.


If I unplug and plug again (the USB plug, leaving the GC pad inserted in port 1 of the Adapter) evtest is showing up the adapter:

Can you check here if that will work for you?

That’s what I fear. It’s a configuration handled entirely by Dolphin, yet the way Batocera assigns other controllers to Dolphin is by utilising its controller profiles. So if you’re using an ordinary GameCube for Wii U adapter, this gets bypassed.

It might be possible to activate passthrough in a similar fashion to Bluetooth passthrough with udev rules: https://wiki.batocera.org/systems:wii#using_bluetooth_passthrough, https://wiki.dolphin-emu.org/index.php?title=How_to_use_the_Official_GameCube_Controller_Adapter_for_Wii_U_in_Dolphin#Linux and finally https://wiki.batocera.org/udev_rules

Thank you very much.

I write down the process in order to help other people that could search for this issue.

1. Create file 51-gcadapter.rules in /userdata/system/udev/rules.d/
2. Open that file and paste the following into it:

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="0337", MODE="0666"

3. Restart PC

(Batocera v40)
