Subject: [34-stable regression] USB delay init quirk causes device events
 loss

Hi,

this commit:
commit 93362a875fc69881ae69299efaf19a55a1f57db0
Author: Phil Dibowitz <phil@...m.com>
Date:   Thu Jul 22 00:05:01 2010 +0200

    USB delay init quirk for logitech Harmony 700-series devices

causes a lot of pain for users who loose events from their input devices:
https://bugzilla.novell.com/show_bug.cgi?id=638200

opensuse 11.3 uses 2.6.34 stable and that's how the patch got there.
Reverting it makes it work again.

The problem is that the patch shuffles with usb_detect_quirks which used
to disable autosuspend by default. Apparently it no longer does.

regards,
