nikitathedogTry this as well at the command prompt in raspberry pi. Type LSUSB and hit enter. This will give you a list of what raspberry pi can recognize that is plugged in and let you know if it can read your hardware as well as verify what is plugged into each usb port.
I have been messing around with trying to figure out why MAME will not recognize my trackball. I verified the tests above awhile back and they work. I have done all the set up suggested above but in MAME I can't get the trackball recognized. The LSUSB test I performed and confirmed that at least the pi can recognize the trackball hardware.
But now I have a new problem using Motion Blue V5, I have been using AdvanceMAME and the 0.106 romset (which is correct). Using the AdvanceMAME 1.4 emulator which is supposed to support the trackball. Roms are loaded in the mame-advmame folder which now they load, but my controllers no longer work as well as the buttons nor the plugged in keyboard so when I try to launch a game I'm stuck at the game splash screen and can't enter coin or start or even tab.
I also have a couple of questions – 1. why under retropie/configs/all/retroarch/autoconfig do i have 2 cfg files, one for DragonRise Inc and one for USB, 2-axis8-buttongamepad? I know the dragonrise is for the 2 usb encoders I have for sticks and buttons but what is he other one for? Is this for the Ultimarc trackball? I would not think so as when I go into the .cfg file for each it looks like a joy stick button set up, except in this case the buttons are set different and the dragonrise has a current modified date on the file. 2. If there is a .cfg for the sticks and buttons shouldn't there be a .cfg for the trackball that has 2 buttons?
I have messed around with a couple of files to get this working and nothing. So I have a couple options:
1. Start over and reload Motion Blue V5 and advanceMAME roms and see if that works
2. Start over and reload Motion Blue V5 and MAME 2003, see if that works
3. Abandon Motion Blue V5 and go back to the latest version of Retro Pi and either versions of MAME
