Problems using trackball with MAME

[Pfredd]

I am trying to use a Kensington USB trackball with MAME2003 to play the game Major Havoc.

If I plug in a USB mouse, the mouse works as the left-right spinner. However, if I try it with the trackball, it does not work.

Running the game with verbose logging produces the following:

With the USB Mouse:
[INFO] [Video]: Graphics driver did not initialize an input driver. Attempting to pick a suitable driver.
[INFO] [udev]: Keyboard #0 (/dev/input/event0).
[INFO] [udev]: Mouse #0 (/dev/input/event1).
[INFO] [udev]: Mouse #1 (/dev/input/mouse0).

With the Trackball:
[INFO] [Video]: Graphics driver did not initialize an input driver. Attempting to pick a suitable driver.
[INFO] [udev]: Keyboard #0 (/dev/input/event0).
[ERROR] [udev] Failed to open device: /dev/input/event1 (Success).

Note the "Failed to open device"

Any pointers on where I can look to resolve this issue?

One other point.

If I do a cat /dev/input/event1 and roll the trackball, I do get junk rinting on the terminal screen.

So it appears that Raspbien is able to access the device.

Switching to AdvanceMAME resolved this issue.
