软件基于Android的配件在Windows [英] Software based Android accessory on Windows
问题描述
我想打开我的电脑变成一个Android配件使用我的应用程序。因此，而不是一个专门的硬件，这将只是电脑，将手机切换到辅助模式，从而启动与主机的硬件相关的部分手机的Java应用程序，并创建一个沟通渠道。
I would like to turn my computer into an Android accessory using my application. So instead of a specialized hardware this will be just PC that will switch the phone into accessory mode, thus launching some Java app on the phone associated with the host hardware and create a communication channel.
我已经找到了样品code （加上一些Java的Android应用程序），这样做在Linux上使用libusb的。它的工作原理是开放使用标准的VID和PID的手机。然后它发送href="http://developer.android.com/guide/topics/usb/adk.html#start">命令打开的附件模式一个
I've found a sample code (plus some Java Android app) to do this on Linux using libusb. It works by "opening" the phone using the standard VID and PID. Then it sends a command to turn on the accessory mode, along with the metadata like model, version etc.
如果手机支持附件模式，那么它会断开并重新枚举了不同的PID。样品code，则检查其是否确实，并打开新的设备。
If the phone supports accessory mode it'll then disconnect and reenumerate with a different PID. The sample code then checks if it did and opens the new device.
不过，我试图让这个运行在Windows上。我发现了几个USB库，如 LibUsbDotNet ，但他们似乎都需要使用了WinUSB设备/ libusb的驱动程序。我用的LibUsbDotNet一个工具生成的libusb驱动程序我的手机，在旧通用的可移动驱动器使用一个安装。但是，这意味着我现在不能访问手机作为一个可移动驱动器时，我想，所以这不是一个解决方案。
However, I'm trying to get this running on Windows. I've found a few USB libraries, like LibUsbDotNet, but they all seem to require the device using a WinUSB/libusb driver. I've used a tool in LibUsbDotNet to generate a libusb driver for my phone, installing it over the old generic removable drive one. But this means I now can't access the phone as a removable drive when I want to, so this is not a solution.
有没有一种方法（preferably库），可以打开基于VID和PID的任何连接的USB设备，然后派几个原始的命令呢？
在该装置将用不同的PID，我可以用它来创建自己的了WinUSB驱动程序，所以这不是一个问题重新枚举。我只需要通过注入一些命令/各地默认的驱动程序打开附件模式。
After that the device will reenumerate with a different PID, which I can use to create my own WinUSB driver, so that is not an issue. I just need to inject some commands through/around the default driver to turn the accessory mode on.
（我会preFER .NET解决方案，但任何Windows是不错，我可以写我自己的Interop包装）
(I would prefer .NET solution, but anything Windows is fine and I can write my own interop wrapper)
推荐答案
我也在寻找一个类似的解决方案。我试过的Linux版本，用的libusb，很少hickups，能够与设备进行通信。 虽然搜索的解决方案，在Windows上我试过很多黑客。 如果需要在ADK模式与设备进行通信，我需要发一些供应商的命令，现在这个我需要做的，而其在大容量存储模式连接。这是不可能使用大容量存储驱动程序。我试图让连接的USB设备节点手柄，看看是否可以发送厂商的命令，但我只能文件中获取描述符请求。于是我就丑的方法，取代大容量存储驱动程序的libusb-win32的，看到它可以做同样的，是的，它的工作，但根本不是一个很好的解决方案。
I am also searching for a similar solution. I tried the Linux version, with libusb, with little hickups, was able to communicate with the device. While searching for the solutions on windows I tried many hacks. If need to communicate with device in ADK mode, I need to send several Vendor Commands, now this I need to do while its connected in Mass Storage mode. This is impossible using Mass Storage driver. I tried to get the Node handle of connected USB device to see if could send vendor command, but there I could only file Get Descriptor requests. So I went ugly method, replaced mass storage driver with libusb-win32, to see it could do the same, YES, it worked, but not at all a good solution.
仍在寻找。
