AW: Controlling hardware with lua (via USB interface)?

[<Goetz.Kluge@...>]

Here 2 devices, which one could control via USB:

http://www.beyondlogic.org/usb/pdiusbd11.pdf (USB / I2C)
http://www.gigatechnology.com/files/Usbmod2.pdf (USB / parallel)

Then the remaining question is how to access USB devices via LUA.

Best regards

I need bidirectional access (unfortunately under Windows) to a port of a PC in order to control 2 pins. This is for emulating an I2C-interface.

As the parallel interface has no long term future, I would like to use USB. Here are these alternatives:
(1) Direct bitbanging (violating the USB spec),
(2) Driving via USB an IC which does USB/parallel-IO conversion,
(3) Driving via USB an IC which does USB/I2C conversion.

Any hints on how to do that with Lua under Windows?
