Hi folks,

Apologies if I've missed the solution to this in my search of the
mailing list's archives, but I'm getting a "No backend available"
error when using pyusb-1.0.0-a0 with libusb-1.0.8. Both compiled fine
and I see all the requisite files in /usr/local/lib (
libusb-1.0.0.dylib, libusb-1.0.a, libusb-1.0.dylib, libusb-1.0.la ),
but:

Python 2.6.2 (r262:71600, Apr 16 2009, 09:17:39)
[GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import usb; usb.busses()

line 819, in find
    raise ValueError('No backend available')
ValueError: No backend available


Any suggestions?
