From 630aa3cfd5f0bae9547fe7dff175d7323d60140d Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 23 Jan 2006 17:17:21 -0500 Subject: [PATCH] [PATCH] USB: UHCI: No FSBR until device is configured Some USB devices don't enumerate well with FSBR turned on. This patch keeps devices on the low-speed part of the schedule (which doesn't use FSBR) until they have been fully configured.
