Hello,

I just want ask a commands in VB6 and VC# in accessing usb port.

Thank you for your bright ideas.

Jezreel :wink:
 

You don't say what USB device you wish to communicate with. The class of that device and the device driver associated with that device will dictate how you can access it in VB.

See the book "USB Complete" by Jan Axelson.

See the following links:

1. Free VB, C++ etc. DLL and demo software E-USB PC-ports kits:

We can adopt a different approach, whose design complexity decreases, but requires addition of few external hardware components : That´s a bridge UART/USB.
At this case, programming at PC side, is performed by standard Serial communications API routines.
Even some professional products make use of that solution, like Modems.
The USB communication directly between uC and PC is suited when the uC already contains a USB hardware module inside.
