Off hand do you know what device file in /dev would represent the USB port(s)? On my laptop I only have one USB. On the PC I will be using for the POS there are two. I looked in /dev/input, but I am not sure which one I need to work with. > I thought you were talking about a Java app that needed to access > the cash drawer, system not revolving around driver.

I would love to be able to access the cash drawer directly from Java and not touch C at all. That would be great if I do not need a driver. I may at some point port the POS to GTK using C++. For now getting the cash drawer to open via Java on Linux would really save my butt. I really do not know how to proceed from here. Other than to do research on HID compliant devices and how HID in general works with in Linux. Any input, links, comments, etc. are greatly appreciated. -- Sincerely, William L.
