[avrdude-dev] Support for custom purpose built programmer |

Hello. I hope this is a good place to post.
I'm designing a custom interface board for end-users of a particular device.
That device contains an Atmega64 and needs frequent flashing by end user, so
my (current) interface board is basically a stock USBasp that is permanently
installed on the device.
My new interface board is going to have much more functionality for the
end-user so I can't follow simple stock USBasp. I want to base it on an
Atmega32U4 so I can take advantage of the bootloader so that my custom
interface can, itself, be updated frequently without a standalone ISP
programmer (so the target device gets updated via my interface board, and my
interface board itself gets updated via USB).
The end-user is already using avrdude to flash the device via the usbasp and
I don't want to change that. So I guess my question is... can I be
confident that avrdude can be configured to use my custom board? I'm trying
to figure out HOW I can put usbasp onto an Atmega32U4 but I'm not really
sure how that works or how the device is recognized by Windows with built-in
USB.
This will be the first time I have any experience with AVR USB chip so sorry
if this is a stupid question.
Thanks.
