USB delay init quirk for logitech Harmony 700-series devices
commit 93362a875fc69881ae69299efaf19a55a1f57db0 upstream. The Logitech Harmony 700 series needs an extra delay during initialization. This patch adds a USB quirk which enables such a delay and adds the device to the quirks list. Signed-off-by: Phil Dibowitz <phil@ipom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
