Re: [avrdude-dev] Compiling avrdude with libusb

[David Hoerl]

I am using this library right now. I posted on it a short while ago. You 
need libusb and a lib-compat that provides glue functions that map into 
the old libusb:

(my previous post)

Sending this for the archives - had good luck getting libusb-1.0.3 and 
the compatibility library (which maps the new library calls into what 
avrdude expects from libusb.0.1). Its seems faster when downloading but 
didn't really measure it.

For OSX Mac users, a note: if you use a portable, as I do, both old and 
new libusb libraries try to get info out of suspended USB devices like 
the camera. This adds many seconds of delay before the download starts. 
I edited the darwin_usb.c file in libusb.1.0, and essentially commented 
out code. This resulted in a much much faster download.
