I am dissapointed about the feedbacks? Touchscreens are more and more common and important today... so I am surprised about the less feedback.
I have also a USB Touchscreen with Atmel Controller mXT1188s, and that Controller works without Problem on Linux / Raspberry... so I guess that your USB Simulator use a old or not up to date Describtor?
Could anybody help me what I can try or change on the descriptor or USB code?
Here the feedback from raspberry community:
We don't have the resources to investigate Teensy and what it needs in order to work on Raspbian. I suggest you ask the Teensy community if one of them can explain exactly what is needed, or at least what the problem is.
One thing you could try yourself is running xev under Raspbian and Ubuntu Mate to see which X events are generated in response to touch screen activity. xev > touch_log.txt will capture the events to a file - try working through the same activities on both platforms in a systematic way, then comparing the log files. If nothing else it may show whether X events are stopping no Raspbian or whether they are still being generated and the GUI is locking up.
thank you very much
