How can USB adapter’s parallel port use with controlling LEDs?

C#

Hello everybody,

I would like to implement I/O Ports Uncensored - 1 - Controlling LEDs (Light Emiting Diodes) with Parallel Port (http://www.codeproject.com/KB/cs/csppleds.aspx[^]) project. I only have a laptop computer with USB connection to Printer Adapter and the project doesn't work well.

I think it maybe because the USB adapter's Parallel LPT port does not have IO address, and it can't remap to 278, 378, or 3BC legacy ISA address either.
So I can't use inpout32.dll.

How is it possible to solve this to use USB adapter's parallel port to this project?
For example if it could be solved with another .dll or other solutions are welcomed.

Thank you very much for your help.
