From a2f9bff99878225dec6a3d4995ab1b993ab649e2 Mon Sep 17 00:00:00 2001 From: Stefano Babic Date: Mon, 18 Oct 2010 10:23:05 +0200 Subject: [PATCH] MX31: add delay between USB port setup and reset Sometimes a usb tree is not popolated after a system reset. It seems a delay is required after setting the USB ports for the MX.31 before resetting the ehci controller.
