// The Trezor devs had the foresight to add the string version as a new message
// code instead of replacing the binary one. This means that the proto file can
// actually define both the old and the new versions as optional. Please ensure

// - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor

// Options
// Each of the definitions above may have "options" attached. These are
// just annotations which may cause code to be generated slightly differently
// or may contain hints for code that manipulates protocol messages.
//
// Clients may define custom options as extensions of the *Options messages.
// These extensions may not yet be known at parsing time, so the parser cannot
// store the values in them. Instead it stores them in a field in the *Options
// message called uninterpreted_option. This field must have the same name
// across all *Options messages. We then use this field to populate the
// extensions when we build a descriptor, at which point all protos have been
// parsed and so all extensions are known.
//
// Extension numbers for custom options may be chosen as follows:
// * For options which will only be used within a single application or
// organization, or for experimental options, use field numbers 50000
// through 99999. It is up to you to ensure that you do not use the
// same number for multiple options.
// * For options which will be published and used publicly by multiple
// independent entities, e-mail protobuf-global-extension-registry@google.com
// to reserve extension numbers. Simply provide your project name (e.g.
// Objective-C plugin) and your project website (if available) -- there's no
// need to explain how you intend to use them. Usually you only need one
// extension number. You can declare multiple options with only one extension
// number by putting them in a sub-message. See the Custom Options section of
// the docs for examples:
// https://developers.google.com/protocol-buffers/docs/proto#options
// If this turns out to be popular, a web service will be set up
// to automatically assign option numbers.

// - A location may refer to a repeated field itself (i.e. not to any
// particular index within it). This is used whenever a set of elements are
// logically enclosed in a single code segment. For example, an entire
// extend block (possibly containing multiple extension definitions) will
// have an outer location whose path refers to the "extensions" repeated

// logical declaration is spread out across multiple places. The most
// obvious example is the "extend" block again -- there may be multiple
// extend blocks in the same scope, each of which will have the same path.
// - A location's span is not always a subset of its parent's span. For
// example, the "extendee" of an extension declaration appears at the
// beginning of the "extend" block and is shared by all extensions within
// the block.
// - Just because a location's span is a subset of some other location's span
// does not mean that it is a descendent. For example, a "group" defines
// both a type and a field in a single declaration. Thus, the locations

# Gopher Interface Devices (USB HID)
The `hid` package is a cross platform library for accessing and communicating with USB Human Interface
Devices (HID). It is an alternative package to [`gousb`](https://github.com/karalabe/gousb) for use
cases where devices support this ligher mode of operation (e.g. input devices, hardware crypto wallets).
The package wraps [`hidapi`](https://github.com/signal11/hidapi) for accessing OS specific USB HID APIs
directly instead of using low level USB constructs, which might have permission issues on some platforms.
On Linux the package also wraps [`libusb`](https://github.com/libusb/libusb). Both of these dependencies
are vendored directly into the repository and wrapped using CGO, making the `hid` package self-contained
and go-gettable.
Supported platforms at the moment are Linux, macOS and Windows (exclude constraints are also specified
for Android and iOS to allow smoother vendoring into cross platform projects).
## Cross-compiling
Using `go get` the embedded C library is compiled into the binary format of your host OS. Cross compiling to a different platform or architecture entails disabling CGO by default in Go, causing device enumeration `hid.Enumerate()` to yield no results.
To cross compile a functional version of this library, you'll need to enable CGO during cross compilation via `CGO_ENABLED=1` and you'll need to install and set a cross compilation enabled C toolkit via `CC=your-cross-gcc`.
## Acknowledgements
Although the `hid` package is an implementation from scratch, it was heavily inspired by the existing
[`go.hid`](https://github.com/GeertJohan/go.hid) library, which seems abandoned since 2015; is incompatible

to give credit to the author of said package too.
Wide character support in the `hid` package is done via the [`gowchar`](https://github.com/orofarne/gowchar)
library, unmaintained since 2013; non buildable with a modern Go release and failing `go vet` checks. As
such, `gowchar` was also vendored in inline (copyright headers and origins preserved).

/*
* poll() and pipe() Windows compatibility layer for libusb 1.0
*
* The way this layer works is by using OVERLAPPED with async I/O transfers, as
* OVERLAPPED have an associated event which is flagged for I/O completion.
*
* For USB pollable async I/O, you would typically:
* - obtain a Windows HANDLE to a file or device that has been opened in
* OVERLAPPED mode
* - call usbi_create_fd with this handle to obtain a custom fd.
* Note that if you need simultaneous R/W access, you need to call create_fd
* twice, once in RW_READ and once in RW_WRITE mode to obtain 2 separate
* pollable fds
* - leave the core functions call the poll routine and flag POLLIN/POLLOUT
*
* The pipe pollable synchronous I/O works using the overlapped event associated
* with a fake pipe. The read/write functions are only meant to be used in that
* context.

GNU LESSER GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.
0. Additional Definitions.
As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.
"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.
An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.
A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".
The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.
The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.
1. Exception to Section 3 of the GNU GPL.
You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.
2. Conveying Modified Versions.
If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:
a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or
b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.
3. Object Code Incorporating Material from Library Header Files.
The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:
a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the object code with a copy of the GNU GPL and this license
document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:
a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.
b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.
c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.
1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.
e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)
5. Combined Libraries.
You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:
a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.
b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.
6. Revised Versions of the GNU Lesser General Public License.
The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.
If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

# Yet another USB library for Go
The `usb` package is a cross platform, fully self-contained library for accessing and communicating with USB devices **either via HID or low level interrupts**. The goal of the library was to create a simple way to find-, attach to- and read/write form USB devices.
There are multiple already existing USB libraries:
* The original `gousb` package [created by @kylelemons](https://github.com/kylelemons/gousb) and nowadays [maintained by @google](https://github.com/google/gousb) is a CGO wrapper around `libusb`. It is the most advanced USB library for Go out there.
* Unfortunately, `gousb` requires the `libusb` C library to be installed both during build as well as during runtime on the host operating system. This breaks binary portability and also adds unnecessary hurdles on Windows.
* Furthermore, whilst HID devices are supported by `libusb`, the OS on Macos and Windows explicitly takes over these devices, so only native system calls can be used on recent versions (i.e. you **cannot** use `libusb` for HID).
* There is a fork of `gousb` [created by @karalabe](https://github.com/karalabe/gousb) that statically linked `libusb` during build, but with the lack of HID access, that work was abandoned.
* For HID-only devices, a previous self-contained package was created at [`github.com/karalabe/hid`](https://github.com/karalabe/hid), which worked well for hardware wallet uses cases in [`go-ethereum`](https://github.com/ethereum/go-ethereum). It's a simple package that does it's thing well.
* Unfortunately, `hid` is not capable of talking to generic USB devices. When multiple different devices are needed, eventually some will not support the HID spec (e.g. WebUSB). Pulling in both `hid` and `gousb` will break down due to both depending internally on different versions of `libusb` on Linux.
This `usb` package is a proper integration of `hidapi` and `libusb` so that communication with HID devices is done via system calls, whereas communication with lower level USB devices is done via interrupts. All this detail is hidden away behind a tiny interface.
The package supports Linux, macOS, Windows and FreeBSD. Exclude constraints are also specified for Android and iOS to allow smoother vendoring into cross platform projects.
## Cross-compiling
Using `go get`, the embedded C library is compiled into the binary format of your host OS. Cross compiling to a different platform or architecture entails disabling CGO by default in Go, causing device enumeration `hid.Enumerate()` to yield no results.
To cross compile a functional version of this library, you'll need to enable CGO during cross compilation via `CGO_ENABLED=1` and you'll need to install and set a cross compilation enabled C toolkit via `CC=your-cross-gcc`.
## Acknowledgements
Although the `usb` package is an implementation from scratch, HID support was heavily inspired by the existing [`go.hid`](https://github.com/GeertJohan/go.hid) library, which seems abandoned since 2015; is incompatible with Go 1.6+; and has various external dependencies.
Wide character support in the HID support is done via the [`gowchar`](https://github.com/orofarne/gowchar) library, unmaintained since 2013; non buildable with a modern Go release and failing `go vet` checks. As such, `gowchar` was also vendored in inline.
Error handling for the `libusb` integration originates from the [`gousb`](https://github.com/google/gousb) library.
## License
This USB library is licensed under the [GNU Lesser General Public License v3.0](https://www.gnu.org/licenses/lgpl-3.0.en.html) (dictated by libusb).
If you are only interested in Human Interface devices, a less restrictive package can be found at [`github.com/karalabe/hid`](https://github.com/karalabe/hid).

* libusb is <em>not</em> designed to work across fork() calls. Depending on
* the platform, there may be resources in the parent process that are not

* addition, since the parent and child will share libusb's internal file

* process's \ref libusb_context to get into an inconsistent state.
*
* On Linux, libusb's file descriptors will be marked as CLOEXEC, which means
* that it is safe to fork() and exec() without worrying about the child
* process needing to clean up state or having access to these file descriptors.

*
* For USB pollable async I/O, you would typically:
* - obtain a Windows HANDLE to a file or device that has been opened in

* - call usbi_create_fd with this handle to obtain a custom fd.
* - leave the core functions call the poll routine and flag POLLIN/POLLOUT
