From 2b8e8d2671227473c9698859db38fefa328b87d0 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 17 Feb 2016 13:34:22 -0200 Subject: [PATCH] mx7dsabresd: Make 'ums' command functional When running the 'ums' command we get: => ums 0 mmc 0 UMS: disk start sector: 0x0, count: 0xe18000 g_dnl_register: failed!, error: -22 ERROR: g_dnl_register failed at common/cmd_usb_mass_storage.c:107/do_usb_mass_storage() Fix this by initializing USB OTG1 port as USB device mode instead of host.
