From d5a24d8b53d350364bd429b7104ec369b817e4b8 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Wed, 28 Sep 2016 11:24:09 +0200 Subject: [PATCH] colibri_t20: fix usb operation and controller order Without this patch the following error will be shown: Colibri T20 # usb start starting USB... No controllers found This patch fixes USB operation and also the controller order as the CI UDC driver may only be instantiated on the first aka OTG port.
