[dorkbotpdx-blabber] Does benito5 only program but not debug AVRs

[Transistor Toaster]

Don,
> Which at90usb162 board are you using?
Actually, I took the at90usb162 all by itself and wired it up using the
Benito5 schematic plus the AT90USBKey schematic
as starting points cutting everything out until I had the minimum to
achieve a "Hello world" of a flashing LED.

My current goal is to be working with a larger pin count ATMEGA, so I
will not be able to rely on FLIP anymore.
I'm going to give this
http://www.scienceprog.com/build-your-own-avr-jtagice-clone/ a try.
