From 955a260829b5848fa90721678bab003234c93356 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Fri, 26 May 2006 10:17:03 -0700 Subject: [PATCH] [PATCH] USB: more pegasus log spamming removed Remove more log spamming from pegasus: stop talking to the device once we see ENODEV reported. It may take a while before khubd notifies us.
