>Description:

After recently updating pkgsrc, xsane no longer recognizes USB scanners.

uscanner0 at uhub3 port 2
uscanner0: vendor 055f product 0001, rev 1.00/1.00, addr 4

This used to work with older versions (most likely libusb is the issue).

>How-To-Repeat:
Try to use a USB scanner on NetBSD.
