That's been my understanding, too.

But what do we have to do for this?  The configure script only tries
to test-compile a small code snippet that includes "usb.h", creates a
reference to usb_get_string_simple(), and then tries to compile and
link this against -lusb.  It doesn't care whether this usb.h and -lusb
come from an original libusb-0.1, or from a wrapper (or from an
OS-supplied API-compatible rewrite, as in FreeBSD).  The libusb 1.0
file and function names have been deliberately chosen to be different,
so there's no confusion.  (Besides, avrdude already starts detecting
libusb 1.0, but by now, it's only used for USBasp.)
