2 * Linux host USB redirector
4 * Copyright (c) 2005 Fabrice Bellard
6 * Copyright (c) 2008 Max Krasnyansky
7 * Support for host device auto connect & disconnect
8 * Major rewrite to support fully async operation
10 * Copyright 2008 TJ <linux@tjworld.net>
11 * Added flexible support for /dev/bus/usb /sys/bus/usb/devices in addition
12 * to the legacy /proc/bus/usb USB device discovery and handling
14 * (c) 2012 Gerd Hoffmann <kraxel@redhat.com>
