Developer a USB plugin without an harware.

[madfly]

Hi, I wanted to start developing a plug-in for Mach3 that could communicate with USB.
I have seen several examples on the forum and was able to configure Visual Studio 2008 Express edition to develop code.
Now my problem is figuring out how to configure Mach3 to send the commands through the USB interface without having yet linked to a PC, I tried to recover the data sent with Engine-> OutSigs I can not receive anything because my laptop don't have a LPT port (I things!!!:( ) or with MainPlanner-> Movements [Engine-> TrajIndex]. DDA1 [axis] but I get the data but can not figure out how to use them, also slows the implementation of GCode.

Can you help?

greetings

Just to bump this post and I also would like to know if there is a particular forum here that deals with USB in general, and if anything has been done with I2c interfacing etc.
And where the VS2008 code would be located here?

Well, you will not find much about USB as such here - we are basically interested yoin using it as data pipe.
For source code - see examples in the Mach SDK
