How can we access the USB port to communicate with USB
devices (read/write) using VB.NET ?
You want to talk to the port directly (raw data), or do you want to talk to
the driver (which would interpert the raw data for you)?
If you want to talk to the driver, you need to contact the manufacturer, or
if it is a standard device, such as a digital camera, then you need to use
the appropriate windows services (for example, you would use WIA for a
scanner/camera).
If you want the raw data, I would imagin that you could use the windows USB
communication functions, but I have no idea what DLL these are hidden in. I
would start by looking up USB communications in the Platform SDK on MSDN
(msdn.microsoft.com).
HTH,
