> Hi,
> I'm currently running imedialinux-6.0.4-alix-vga on my Alix 3c3. I also have an Elotouch 1545L USB 15" touchscreen monitor.
> 
> I've looked into the touchscreen support drivers that come with iMedia, but the Elo drivers seem to be for serial interfaces (ie. elographics_drv.so)
> 
> I used the newest drivers from Elotouch, which includes the elo_drv.so module. I am able to compile the kernel module elousb.ko and the actual drivers work, the part that doesn't is in xorg. I can load the elosub.ko module and run the calibration program. The calibration program works with the targets moving when I touch the screen. However the mouse doesn't move. I've modified the xorg.conf as per the driver's readme. What I get is:
> 
> (II) LoadModule: "elo"
> (II) Loading /usr/lib/xorg/modules/input//elo_drv.so
> (II) Module elo: vendor="X.Org Foundation"
>         compiled for 4.3.99.902, module version = 1.0.0
>         Module class: X.Org XInput Driver
>         ABI class: X.Org XInput driver, version 0.7
> (EE) module ABI major version (0) doesn't match the server's version (2)
> (II) UnloadModule: "elo"
> (II) Unloading /usr/lib/xorg/modules/input//elo_drv.so
> (EE) Failed to load module "elo" (module requirement mismatch, 0)

> I can't understand what the "module requirement mismatch" means. I thought it had to do with the wrong versions of xorg, but I've tried this with imedia 6.0.0, 6.0.1, 6.0.3 and 6.0.4. The xorg versions here range from 7.1 to 7.3. One of the versions should have worked, but all resulted in the same error.
