From b13296c6617f22e8c0174a7af32780617db0e680 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Tue, 27 Sep 2005 10:38:54 -0700 Subject: [PATCH] updates for "controller suspended" handling Reject URBs to _all_ devices when their host controllers are suspended; even root hub registers will be unavailable. Also, don't reject urbs to root hubs in other cases; the only upstream link is through that controller (on PCI or whatever SOC bus is in use).
