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
