From 7ceec1f1d26f966c0816b86a1aab1e0b3b208757 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Fri, 26 Jan 2007 14:26:21 +0100 Subject: USB: add a blacklist for devices that can't handle some things we throw at them. This adds a blacklist to the USB core to handle some autosuspend and string issues that devices have. Originally written by Oliver, but hacked up a lot by Greg.
