From a1d31077d06d47233d2bd7002cf65d5ee9b5e501 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 6 Jan 2015 14:27:42 +0100 Subject: [PATCH] config_distro_bootcmd.h: Remove unnecessary magic to avoid repeated USB scans Now that "usb start" will only start usb if not already started, we can simply call "usb start" whenever we (may) need access to usb devices, and it will only actually scan the bus at the first call.
