USB Mouse



  • Hey,
    I am using Qt application on TI's DaVinci TMS320DM6446 board.
    I need USB mouse to control my application.

    I have enabled all options related to USB mouse in make menuconfig. Also the usb mouse is working when we check it in /dev/input/mice on our target board.

    But on actual application, the USB mouse is not working. Pointer is visible. I am using Logitech USB Mouse, so which is the "driver" option for Logitech Mouse in command

    export QWS_MOUSE_PROTO=driver:/dev/input/mice

    Do I have to insert closeMouse(),openMouse () functions ?

    Does Qt support only for PS2 mouse ?

    Thanks in advance.



  • Have you checked that device is present in "/dev" folder? You can test the device in a console with "od /dev/yourdevice". If there is no output, you have the wrong device!



  • We checked the USB Mouse with command
    "cat /dev/input/mice" on our target board.
    And it's working.



  • bq. export QWS_MOUSE_PROTO=driver:/dev/input/mice

    Which driver have selected? This drivers are included: IntelliMouse, Microsoft, VR41xx, LinuxTP, Yopy, Tslib.



  • We tried with MouseMan....Because it is related with Logitech....

    But that didn't work.

    Thanks.



  • Why you didn't try all? Maybe another one works!?!? I'm always try all, why not!



  • Yes, I tried, same result with all.



  • Did you try without setting QWS_MOUSE_PROTO? So qws tries its default devices?



  • Yes, I did it too.

    And also I tried for QWS_MOUSE_PROTO=Auto:/dev/driver/mice
    In that sense it's not trying for default devices.
    Thanks..



  • Is there anyone who knows if there is anyway to interface to a HID device (e.g. mouse, keyboard) via Qt in Windows?
    THANKS

    Hi,

    You should rather open a new thread with your question rather than dig old unrelated thread, you'll have more chance to have an answer.
