Bug#594330: libusb2 doesn't detect any devices

[David Moles <molesd@rocketmail.com>]

Package: libusb2
Version: 8.1-3
Severity: grave
Tags: patch

Hi!

libusb2 is unusable because libusb_get_device_list doesn't detect any devices. This happens because libusb20_be_alloc_ugen20 is disabled.

This problem can be reproduced with lsusb from http://code.google.com/p/segin-utils/source/browse/trunk/freebsd-utils/lsusb-libusb.c.

I'm providing a patch.
