-moved usb device operations into usb_operations module
new file: source/usb_operations.c
new file: source/usb_operations.h
-creation of usb_operations module
-currently handles libusb open/close and retrieving INL retro-prog
usb handle.
-moving returnvalue "rv" declaration/init earlier to ensure initization.
-adding notes to user if LIBUSB_ERROR_ACCESS as it's expected on linux.
modified: udev-rule-help/Readme.txt
-including expected libusb error if user doesn't have access.
host\include\dbg.h: reversing DEBUG logic.
host\source\inlprog.c: working through making code more robust with proper
error checking via "Zed's AWESOME debug macros" ;)
Makefile copied from the Makefile I came up with during Zed Shaw's LCTHW
inlretro.c basic usb functionality using libusb 1.0
-searches through usb devices and opens matching VID/PID
-sends vendor xfr command for LED ON/OFF
-closes out usb device prior to exit
-lots of messy comments as notes while learning libusb
