looks like I need to set LIBUSB_SUPPORT
$ LIBUSB_SUPPORT=1 make
And now it is working as described, which is very nice.
+1 mainline
Q: What happens if there are 2 devices plugged in?
I am assuming it uses the first one it finds.
For my usage that is fine.
You might want to add an index or something, although in those cases
the person can just use the devpath. I expect most people will be
using this from a udev rule that acts on the device being plugged in.

libusb project shipped with fxload as an example as well. Not so sure which
version is better.

Carl,
Thanks for testing. I gave you the credit for mentioning
LIBUSB_SUPPORT=1. I forgot about it.
