 BOOTLOADER:
+bootloadHID-master:
 https://github.com/ajd4096/bootloadHID
+fork of original obdev bootloader has option to remove BL switch with timeout.
+
+bootloadHID.2012-12-08:
+https://www.obdev.at/products/vusb/bootloadhid.html
+the original believe it has more upto date V-USB drivers.
+
+Both have identical commandline folders so they're identical on the host side.
+need to have libusb-dev installed can check by typing "libusb-config" in terminal
+will present usage options if installed on your system
+if not installed should report so with suggestion for apt-get:
+	paul@eeepc:~/Dropbox/retro_pgmr/INL-retro-progdump/bootloader/commandline$ libusb-config
+	The program 'libusb-config' is currently not installed. You can install it by typing:
+	sudo apt-get install libusb-dev
+then just run 'make' will hopefully build sucessfully
