Does anyone know if there is an easy way to control USB ports from

device that is connected to a USB port.


I've no idea how access usb on plain dos. So the first step is to find _any_
code that does this from dos, and preferably 32-bit, and then convert it.

So e.g. you could look if there is a libusb for DJGPP. There are
multiple header conversions so you can access it from FPC. e.g.

Since this is uncharted territory, it might not be for the faint of heart.

I made a touchscreen application long time ago for dos. The screen came with a mouselike driver for dos. Most manufacturers will only make windows drivers nowadays. Try running it in a dosbox

There is a unit USB4DOS out there somewhere, but don't expect to much from it.
