USB and Delphi
Posted on 2002-03-07
Okay, I have been trying for the past few days to get a non USB compliant bar code scanner to work through a USB port. The problem is that I have no idea how to actually access the port. I have been able (thanks to Robert Marquardt's code for his HIDController class), been able to catch the plug/unplug events and pull off a GUID, although I doubt that this GUID is valid. Bottom line: does anyone have any idea how I can read and write to the USB as I would a serial port? Any pointers/codes samples are greatly appreciated. I'm willing to increase the points for a working solution.
