Mouse/Trackball udev error

metalhead

I am getting errors when trying to load a trackball supported game in Mame2003, for example centipede. I have read a lot of posts on this topic and tried everything suggested...nothing has worked for me so far.

/dev/shm/runncommand.log snippet;
[ERROR] [udev] Failed to open device: /dev/input/event6 (Invalid argument).
[INFO] [udev]: Mouse #0 (/dev/input/mouse1).
[ERROR] [udev] Failed to open device: /dev/input/event9 (Invalid argument).
[INFO] [udev]: Mouse #1 (/dev/input/mouse2).
[ERROR] [udev] Failed to open device: /dev/input/event4 (Invalid argument).
[INFO] [udev]: Mouse #2 (/dev/input/mouse0).

The trackball in question is mouse 0 / event 4. Works fine when testing, but never in a game.

Details
Pi 3
Mame2003 romset 0.78
Retropie 4.3

Can anyone tell me what the UDEV ERRORS are and how to fix them please?

Apologies for the length of this post, and if I have broken a forum rule, this is my first posting.

Hi All

No takers? I know lots of people have had trouble with setting up a mouse/trackball. Did no-one ever solve their issues?

I can cat /dev/input/*** and find my trackball is mouse0 event4
What does the ERROR failed to open device mean?

Like other posters, I can get the trackball working as a mouse in Amiga emulation and Pi desktop, but never in Mame2003...at least it was working before I upgraded from RP4.2 to RP4.3

I have tried the config in both the Arcade folder and the Mame2003 folder, plus tried changing the config in config/all/retroarch.cfg...none of the changes I make seem to make any difference at all.

Really would appreciate any help with this please.

Thanks

Hi Metalhead

Could you share with us what you did to solve the problem ?

Hello jancolle
And there was me thinking nobody else has ever had this issue...
I simply rolled back to RP4.2 and it's fine. No matter what config I tried in RP4.3 it does not work with a usb trackball, certainly not the one I have. Works fine again. My advice, is don't upgrade. If it ain't broke, you don't need to fix it.

Thanks a lot. I have also tried a lot of configs without any luck, all on 4.3.
I will test with a 4.2 installation.
