From 414e4eb40e9a5decfaa2a5aef9ceac9768b7740b Mon Sep 17 00:00:00 2001 From: Matthias Welwarsky Date: Wed, 6 Apr 2016 10:35:13 +0200 Subject: [PATCH] ftdi: make ftdi_location command depend on libusb1 version MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The function libusb_get_port_numbers(), required for the command ftdi_location, is only available in recent version of libusb1. Compilation will break if the function is not available. This patch enables the command only if libusb1 contains the necessary function.
