Following your link I only see "Compatible with Windows ME/2000/XP/Vista/7" Are you sure it will work with CentOS 6? I don't use it for print anything, but just to switch on my own home alarm as I wrote here: http://www.securitybydefault.com/2011/04/trasteando-con-una-alarma-de-securi... Sorry, it is in spanish, that's my language :) Give it a try with some online translation service.
that style of programming, poking bits at a physical IO device at an assumed port address will not work on anything but a legacy mainboard LPT1 port. any PCI or PCI-E port will be at a dynamic address which you'd have to find via the plug and play device registry, or groping your way through the output of lspci, which it appears you've been doing.. a USB port requires a complex sequence of commands to be sent to the USB controller to send data to the port.
my guess is, the newer kernels have dropped support entirely for ieee1284 devices.
