From 842ef9a98ef8643df87d3ae5664802cd5db2bca0 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 25 Aug 2014 14:02:15 -0600 Subject: [PATCH] usb: ci_udc: implement dfu_usb_get_reset This allows the USB code to determine whether a USB bus reset was issued, which in turn allows the code to differentiate between a detach (return to shell prompt) and a board reset/reboot request.
