Subject: configure.ac: Fix build when libusb-1.0 not available.
X-Git-Tag: libsigrok-0.2.2~92
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=6383365795b8f9a3408315f8726fa75fa25e19d1

configure.ac: Fix build when libusb-1.0 not available.

The Saleae Logic16 needs libusb-1.0, thus disable this driver when
libusb-1.0 cannot be found.
