Drivers with iiyama T2250MTS touch screen on windows 7 embedded

Hello,

I use an iiyama ProLite T2250MTS touchscreen and a Wyse terminal of the type C90LE7 with Microsoft Windows 7 Embedded.  Now the screen works on the good resolution, only the touch-usb function doesn't work.  It does work on a full version of Windows 7 on a normal computer but not on Embedded on my Wyse.

After booting it, I log in as Administrator and see the installed devices in my device management.  Under 'Unspecified', I even find an 'Optical Touch Screen'... Unfortunately, I get no reaction when touching the screen.  

The touch screen is in my device management (under Human Interface Devices) when I tried to install the original iiyama drivers from  their site in my device management, it fails with:

"The folder you specified doesn't contain a compatible software driver for your device.  If the folder contains a driver, make sure it is designed to work with Windows for 32-bit systems."  It's the only driver available for Windows 7 and I've tested it on another Windows 7 32-bit computer and it does its job,  only not in Windows 7 Embedded....

After some googling and forum-search, I found I'd better install the drivers with devcon , so I  tried the following line:

C:\devcon>devcon -r install C:\touchscreen\mt2250mts.inf usb
Device node created.  Install is completed when drivers are updated...
Updating drivers for usb from c:\touchscreen\plt2250mts.inf
devcon failed.

Would I be doing something wrong or does anyone have some golden tip for me?


Thanks in advance!

If the manufacturer doesn't support the windows embedded platform, you have only two ways, first ask the manufafturer to provide ones, or find a similar driver and install it.
Googling around I found this link[1] where they say that Acer haves a device with the same VID/PID (vendor 0408 product 3000 - maybe T230H?). You could see if you can install the acer driver on windows embedded.
I have also found this link [2] that remands to this link[3] that have a compatible driver for windows XP. See if it helps.

Hello HappyCactus,

Thank you very much for your comment.  I have read the forums and tried out both the drivers of the acer and of the HP.  Unfortunately, none of them works.  The HP that seemed to be the solution for the Acer-problems only has an exe-file for Windows XP (the touch-screen part), which doesn't work on Windows 7 embedded...

I have mailed iiyama about this matter, but they mailed me back saying that there were no new drivers in their planning.  I have mailed Wyse and they have redirected me to some forums with tips on usage of 'devcon', but they too had no 'real' solution.  The research on a driver has taken more time than the cost of a new screen, so we will buy an HP with ELO-drivers for this application and dump the iiyama with somebody who works with a full computer (not working on windows embedded)

I will leave this post a few more days open in order to let others comment with pherhaps another solution, otherwise, I'll accept
first ask the manufafturer to provide ones, or find a similar driver and install it.
as an answer, even though in this particular case there wasn't any available...
