From 8d9c4d9ebffe5ed7be34dad7bc4ef4ab6807c501 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 16 Mar 2017 17:13:42 +0100 Subject: [PATCH] USB: serial: io_ti: always require a bulk-out endpoint These devices always require at least one bulk-out endpoint so let core verify that. This avoids attempting to send bulk data to the default pipe when downloading firmware in boot mode. Note that further endpoints are still needed when not in boot mode.
