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