Follow-up Comment #2, patch #7062 (project avrdude):
>Curious, are you aware of patch #6502? I'm not sure whether patch
Yes. this patch is based on a very early version of avrftdi, reworken by
Ville.
I decided to open a new patch, because there are like 3 revisions of avrdude
in between and countless changes/improvements on avrftdi. I hope that wasn't
wrong.

I am also aware of this patch, however bitbanging just plain s****, beacuse
it's awfully slow. Also #6886 DOES rely on the closed source driver (as i
understand it).
avrftdi uses the FT2232 MPSSE engine to speed things up quite a bit.

I understand that concern. However there are 2 drivers for ftdi-devices:
the above-mentioned ftd2xx (the closed source-binary distributed by ftdi) and
an open source driver called libftdi (LGPL, i think), which avrftdi uses.
libftdi uses libusb and sould therefor run everywhere, where libusb works.
