Just the ftdi programming template for icebreaker.
# The Vendor ID and Product ID seem to identify a particular chipset
# to target. I used the libftdi utilities and OS X USB Prober app to
# poke around and figure out what numbers to use.
vendor_id=0x403
product_id=0x6010
# The rest of the fields are settings which can be written to the
# FT2xx with the --flash-eeprom option.
