[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. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
