Joy2Key not reading my controller inputs after update
-
Pi Model or other hardware: 4 4GB
Power Supply used: Official Raspberry Pi power supply
RetroPie Version Used: 4.8.9
Built From: Pre made SD Image on RetroPie website
USB Devices connected: 8bitdo Pro 2 Wired Controller
Controller used: 8bitdo Pro 2 Wired Controller
How to replicate the problem: Update RetropieAfter updating my Retropie, my controller stops working with the blue menus where joy2key would be translating buttons into key presses. Thank you in advance for any help or advice.

Can you run again the debug command and post the output:
python3 /opt/retropie/admin/joy2key/joy2key_sdl.py kcub1 kcuf1 kcuu1 kcud1 0x0a 0x20 0x1b 0x00 kpp knp -d -

The log ouput is truncated, you may want to resize the SSH terminal session to capture the entire output.
I don't see any errors reported and the configuration is loaded as before (Added configuration for known device 8BitDo...). What happens if you're pressing the buttons while the script is running, started from the debugging command line ?

@mitu
Here's a pastebin instead.
https://pastebin.com/RRvwV5avIn the meantime i will try to test pressing the buttons with the script running
-
Running the command while the Retropie Setup menu is open makes the buttons work. Exiting the menu back to Emulationstation and then re-entering the Retropie setup menu causes the controller to go back to not working.
-
That's strange, since the same type of command is ran when the menus are started. Does the
runcommandmenu work ? Did you reboot after updating ?EDIT: specifically, when starting RetroPie-Setup dialog menus, the following command is ran:
python3 /opt/retropie/admin/joy2key/joy2key_sdl.py /dev/input/jsX kcub1 kcuf1 kcuu1 kcud1 0x0a 0x20 0x1b 0x09 kpp knpYou can try running with the
-d(debug) parameter to see if any errors are reported, outside of RetroPie-Setuppython3 /opt/retropie/admin/joy2key/joy2key_sdl.py /dev/input/jsX kcub1 kcuf1 kcuu1 kcud1 0x0a 0x20 0x1b 0x09 kpp knp -d -
@mitu I'm going to keep looking for the runcommand menu. I rebooted after updating just now, still not working.
Here's the result of the -d command

Assuming I have the correct runcommand menu, no it does not work in that menu.

Nothing really different than the previous output - no errors logged. Not sure why it's not working though.

OK. While the RetroPie-Setup is running (and the mapping is not working), can you run the following command (via SSH) and post the output:
ps -ef | grep joy2key -

It looks like the
joy2keyutility is not started.I'll take a look at it later on, but in the mean time I have reverted the changes that caused this. Update again RetroPie-Setup and the mapping should be working again.

@mitu Thank you, that helped.
