Hello!
This is a small patch that will let you program the chip via the
Robokits USB Programmer in HID mode. It seems to work with the
existing avrdoper driver but the driver doesn't recognize the programmer
because it looks for a fixed vendor/product id. This patch adds Robokits'
vendor/product id to the checks. In addition I removed the code that performs
a check for vendor/product name. Just for simplicity - if it's required someone
can merge that in.
Greetings,
Janne Junnila
