I am having a similar problem with my touchscreen. I had to get a usb extention cable to connect the usb controller to my carpc(which is mounted in the trunk of my 300m). I'm also curious as to how to remedy this issue. It is being detected in LinuxICE2(but can't calibrate for some reason). In Windows(I have a multiple OS setup) it is no longer recognized since installing it in my car(using the extension cable). Do I need a certain kind of usb extension cable? Must be at least 10' long.
Sorry for Hi Jacking your tread....but we have a similar problem, so I thought it a good idea to try find the answer on the same one...lol!!!
