Externals: Update libusb to 1.0.23-rc1

Now has support for isochronous transfers in the WinUSB backend,
which may or may not work better than the UsbDk backend.

Installation Instructions for Windows
*************************************
If you are compiling for MinGW or cygwin, please refer to the INSTALL file.
If you are using Microsoft Visual Studio:
- Open the relevant solution file in /msvc:
libusb.dsw for MSVC6, libusb_2005.sln for Visual Studio 2005 or 2008,
libusb_2010.sln for Visual Studio 2010,
libusb_2012.sln for Visual Studio 2012 or later,
libusb_wince.sln for Windows CE support in Visual Studio 2005.
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Select your configuration and compile the project
Note that if you are using Visual Studio Express, you may have to install the
Windows SDK to be able to compile the 64 bit version of the library.
If you are using the freely available Windows DDK/WDK (Driver Development Kit)
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Open one of the relevant Free Build or Checked Build prompt for your target
platform
- Navigate to the msvc\ directory where the ddk_build.cmd file is located, and
run 'ddk_build'
- To produce a DLL rather than a static library, use: 'ddk_build DLL'
- To produce a static library that uses LIBCMT[d] instead of MSVCRT[d] (/MT[d]
vs /MD[d] in Visual Studio) use: 'ddk_build /MT'
Note that using the Windows DDK, it is possible to compile both the 32 and 64
bit versions of the library.
If you are building for Windows CE then you will need the Windows CE Standard 5.00 SDK.
Destination directories
***********************
The 32 bit binaries compiled either from Visual Studio or the DDK are placed in
a Win32\ directory at the root of the library
The 64 bit binaries are placed in an x64\ directory
Windows CE binaries are placed in one of the following directories, depending
on the target processor: ARMV4I, MIPSII, MIPSII_FP, MIPSIV, MIPSIV_FP, SH4 or x86.
Troubleshooting
***************
If the compilation process complains about missing libraries, ensure that the
default library paths for your project points to the relevant directories.
If needed, these libraries can be obtained by installing either the latest
Windows SDK or the DDK (Links provided at the end of this file).
For Windows CE it is necessary to install the CE USB Kernel Wrapper driver for
libusb to function on a device.

libusb is a library for USB device access from Linux, Mac OS X,
Windows, OpenBSD/NetBSD and Haiku userspace.
It is written in C (Haiku backend in C++) and licensed under the GNU
Lesser General Public License version 2.1 or, at your option, any later
version (see [COPYING](COPYING)).
libusb is abstracted internally in such a way that it can hopefully
be ported to other operating systems. Please see the [PORTING](PORTING)
file for more information.

Notes related to git compilation:
--------------------------------
If you retrieved the libusb repository from git and are using a gcc based
toolchain, be mindful that you should have the autotools installed (autoconf,
automake) and will need to run either ./autogen.sh or ./bootstrap.sh to produce
the configure file.
The difference between autogen.sh and bootstrap.sh is that the former invokes
configure with a default set of options, and will therefore generate a Makefile,
whereas the latter does not invoke configure at all. If using autogen.sh, note
that you can also append options, that will be passed as is to configure.
OS X-specific notes:
-------------------
Starting with Xcode 4.3, neither Xcode.app nor the Xcode 'command line tools'
includes autotools and so running either autogen.sh or bootstrap.sh will result
in the message:
libtoolize or glibtoolize was not found! Please install libtool.
To proceed, you must find and install it from somewhere.
Alternatively, you can use the Xcode project at Xcode/libusb.xcodeproj.
Notes related to submitting new developments:
--------------------------------------------
If you submit a new development to libusb (eg: new backend), that is unlikely
to fit in a couple of small patches, we would kindly suggest that you create a
public account on github, if you don't have one already, and then fork a new
libusb repository under this account from https://github.com/libusb/libusb.
Then you can create a git branch for your work, that we will be able to better
reference and test.
We also suggest that, if you are planning to bring in a large development, you
try to involve the libusb community early by letting the mailing list know, as
you may find that other people might be eager to help you out.
See http://mailing-list.libusb.info for details on how to join the mailing list.

libusb for Android
==================
Building:
---------
To build libusb for Android do the following:
1. Download the latest NDK from:
http://developer.android.com/tools/sdk/ndk/index.html
2. Extract the NDK.
3. Open a shell and make sure there exist an NDK global variable
set to the directory where you extracted the NDK.
4. Change directory to libusb's "android/jni"
5. Run "$NDK/ndk-build".
The libusb library, examples and tests can then be found in:
"android/libs/$ARCH"
Where $ARCH is one of:
armeabi
armeabi-v7a
mips
mips64
x86
x86_64
Installing:
-----------
If you wish to use libusb from native code in own Android application
then you should add the following line to your Android.mk file:
include $(PATH_TO_LIBUSB_SRC)/android/jni/libusb.mk
You will then need to add the following lines to the build
configuration for each native binary which uses libusb:
LOCAL_C_INCLUDES += $(LIBUSB_ROOT_ABS)
LOCAL_SHARED_LIBRARIES += libusb1.0
The Android build system will then correctly include libusb in the
application package (APK) file, provided ndk-build is invoked before
the package is built.
For a rooted device it is possible to install libusb into the system
image of a running device:
1. Enable ADB on the device.
2. Connect the device to a machine running ADB.
3. Execute the following commands on the machine
running ADB:
# Make the system partition writable
adb shell su -c "mount -o remount,rw /system"
# Install libusb
adb push obj/local/armeabi/libusb1.0.so /sdcard/
adb shell su -c "cat > /system/lib/libusb1.0.so < /sdcard/libusb1.0.so"
adb shell rm /sdcard/libusb1.0.so
# Install the samples and tests
for B in listdevs fxload xusb sam3u_benchmark hotplugtest stress
do
adb push "obj/local/armeabi/$B" /sdcard/
adb shell su -c "cat > /system/bin/$B < /sdcard/$B"
adb shell su -c "chmod 0755 /system/bin/$B"
adb shell rm "/sdcard/$B"
done
# Make the system partition read only again
adb shell su -c "mount -o remount,ro /system"
# Run listdevs to
adb shell su -c "listdevs"
4. If your device only has a single OTG port then ADB can generally
be switched to using Wifi with the following commands when connected
via USB:
adb shell netcfg
# Note the wifi IP address of the phone
adb tcpip 5555
# Use the IP address from netcfg
adb connect 192.168.1.123:5555
Runtime Permissions:
--------------------
The default system configuration on most Android device will not allow
access to USB devices. There are several options for changing this.
If you have control of the system image then you can modify the
ueventd.rc used in the image to change the permissions on
/dev/bus/usb/*/*. If using this approach then it is advisable to
create a new Android permission to protect access to these files.
It is not advisable to give all applications read and write permissions
to these files.
For rooted devices the code using libusb could be executed as root
using the "su" command. An alternative would be to use the "su" command
to change the permissions on the appropriate /dev/bus/usb/ files.
Users have reported success in using android.hardware.usb.UsbManager
to request permission to use the UsbDevice and then opening the
device. The difficulties in this method is that there is no guarantee
that it will continue to work in the future Android versions, it
requires invoking Java APIs and running code to match each
android.hardware.usb.UsbDevice to a libusb_device.
