# This is a BitKeeper generated patch for the following project:
# Project Name: Linux kernel tree
# This patch format is intended for GNU patch command version 2.5 or higher.
# This patch includes the following deltas:
# ChangeSet 1.573.92.13 -> 1.573.92.14
# drivers/usb/misc/usbtest.c 1.1 -> 1.2
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/10/07 david-b@pacbell.net 1.573.92.14
# [PATCH] usbtest: mo'betta devices, control tests
#
# This updates the usbtest driver:
#
# - Supports more devices for the basic i/o tests,
# using full speed ez-usb firmware (and usbtest
# tweaks!) provided by Martin Diehl.
#
# - Adds another test case, which issues control
# messages to devices. There will be further
# updates in this area (control queueing, and
# likely improving usbcore api coverage).
#
# - Adds a "generic device" mode where vendor
# (and optionally product) ids can be given as
# module parameters. Those devices can be used
# for testing control traffic.
