From 9599815de61db104ad21bc61f5e3544d2415c6ee Mon Sep 17 00:00:00 2001 From: Marek Szyprowski <m.szyprowski@samsung.com> Date: Mon, 20 Oct 2014 12:45:32 +0200 Subject: [PATCH] usb: dwc2: gadget: fix enumeration issues Excessive debug messages might cause timing issues that prevent correct usb enumeration. This patch hides information about USB bus reset to let driver enumerate fast enough to avoid making host angry. This fixes endless enumeration and usb reset loop observed with some Linux hosts.
