Thank you very very much for your answer. It sounds very very great. The problem, that I am new, and I do not know, what tools they used. But I asked them and they said they just used a normal pre seted driver, so, I mean, they said, they did not make such a settings what you wrote.
Could you help me where I can download this "EMGD" driver?
And... other informations. We use different operating systems, but we sold all these problematic devices with "Windows 7 Embedded". So, not "Mobile", just plain Windows 7 Embedded. Is this EMGD driver good for this operating system?
((((((((What does it mean "EMGD"?))))))))
Thank you very very much again, I feel the first time, that we are close to the solution.
