From 961906edb549c95f4cc33e4f3dbfd0fcc364954d Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Tue, 20 Dec 2011 15:37:21 +0200 Subject: [PATCH] usb: dwc3: gadget: move us to Default State after reset After a bus reset, we should move our state to Default, in order to be able to re-enumerate again. I only managed to trigger this problem with g_ether by removing the cable after a few transfers had been completed.
