USB code examples

[Avatar Engineer]

I'm new to PureBasic and would like to see example code for implementing USB communications
in a Windows OS. Hopefully, there are some easy methods that work well for both WinXP & Win7
in both 32 & 64 bit. My application would be for connecting remote laboratory instruments.

Well the COMmate library may be of help there... I know you can probably do it with the API as well...

And the last one got me thinking... many devices designed for UB come with their own drivers... Why not just communicate with those drivers?

Library HID_Lib is intended for work with USB HID devices. If only be not afraid of Russian.

Thanks for links !
While most consumer devices may come with host drivers, I'll be connecting
to my own target hardware... The embedded controller code for USB is difficult enough
and the most expedient method is to use RS232 from the target and use a USB
converter cable to the host PC... but I'd like to "Roll my own" this time.

What I did when writing the drivers for my Customer Display was sourceforge and hack a USB to COM driver and open the USB Gadget as a COM3 then write to COM3 (I could read from it as well...)

Sounds good!

can you post the code?

I went to sourcefoge and grabbed these:

http://sourceforge.net/projects/libusb-win32/

http://sourceforge.net/projects/libusb/

A lot of what I did I learned from attempting to use this:

http://sourceforge.net/projects/libusbdotnet/

http://sourceforge.net/projects/npipe/

Code is being used... but you can freely use the sourceforge stuff. Easier in the long run. Just be sure to check license before distributing!

Thanks again,... looks like I've got homework!
