Ultimarc trackball

  • I have plugged in with the USB connector and the Pi will not acknowledge. Do I need to program before? Everything I read it should at least detect as a mouse but I just have my 2 controller setup which is already working The green light is on the UBS adaptor so I figure it’s working. Any ideas? Everyone talks about how easy it is to setup but I have to found any setup that was. Anyway, it it won’t recognize the track ball I can’t go any further anyway. Any help appreciated.

    Please add more info about your system, as detailed in
    What emulator are you trying to use and what game are you trying to start ? There's a fairly detailed setup guide at,-Trackballs,-Lightguns,-and-other-Mouse-Devices/, including instructions on how to test that your trackball is detected and how to configure it in emulators.

  • Musing RetroPie 3b+, it’s not the emulator as I cannot get that far. I have plugged device into the Pi and it doesn’t recognize, I also tried plugging in a mouse and it would not recognize in the configure screen. My though is something is blocking it from adding another controller. I did plug my keyboard in and it works to work through screens.

  • All the test revolve around going into the data and typing in but I have been unable to find a post that shows how to get there. I have seen variations of you must type this in notes to it should work fine once it detects the trackball as a mouse. The Retropie is new to me even though I have reasonable computer skills. The link you gave me in my eyes was absolutely useless. I was hoping for a video somewhere but if I cannot detect the trackball as even a mouse I don’t where to go next.

    To operate RetroPie you'll need a keyboard or a game controller, you can't use RetroPie just with a mouse. The trackball would be used only with a game that supports a trackball/mouse.

  • Got it to work, now I just need to adjust the power level playing golden tee and I will be set. I don’t know if there is a listing here that you can help with but it would be awesome. The 100 yard hits will get old :)

  • Mi got everything working and games word smoothly. Question, trackball is inverted, do you know how to correct? When I take strokes they have very little power, is this a mouse sensitivity adjustment? Where do I find this?
