I think there would be other languages that will suite your needs better such as C since as from your comments I am taking the impression that you need low level communication with USB port!

Well I think that for VB this is it is possible because i had some examples that comunicated with my USB infrared device...But well if you want to use VB I wold recommend you to use an OCX that has this support than import it in VB and work with it...I dont suggest using pure VB code Smile)

Hi crowinu,

Can you clarify if you want to write code for a PC or a PIC as there is no pic that i know of that supports VB/VC?

As for USB coding, i would do a google for a third party control. but i found this on MS which might be interesting reading.

Download the source code and Have a look at the USBSharp class.

If there anything you don't understand feel free to ask.
