Hi!! And Sorry for my bad english and my bad understanding...

I want comunicate the PC with my device...
My device is a data acquisition system controled for PIC microcontroler...
And I need a fast comunication and errors checking...
From this I think it's best to me is Bulk!!
But bulk needs a driver, so I use WinUSB...

And how is a project of my university, and the teacher doesn't want me to use libraries like libusb...
I think the only way is the WinUSB!

And I read the link if you send to me...
In this link has all the functions...
But, it's in C++??

And the header file is created automatically when I use WinUSB??

Thank's a lot!
