From 0517587e5896cef1d5f99d3b24f5f2ca15d952ad Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Thu, 22 Jun 2006 13:29:52 -0700 Subject: [PATCH] [PATCH] USB: get USB suspend to work again Yeah, it's a hack, but it is only temporary until Alan's patches reworking this area make it in. We really should not care what devices below us are doing, especially when we do not really know what type of devices they are. This patch relies on the fact that the endpoint devices do not have a driver assigned to us.
