访问实际硬件(卡)寄存器的代码现在应该进行一些修改，访问模拟设备寄存器的本地变量。
The code that accesses the actual card registers should now be changed to access the local variables that mimic the device's registers.
开发人员编写代码来通过API访问设备，但是一些API目前不可用，比如一个指针api、一个视频API或一个套接字api。
Developers write code to access the device through its APIs, but some APIs are not yet available, such as a compass API, a video API, or a sockets API.
我们还将提供代码片段以展示如何用这两个项目的API访问usb设备。
We'll also offer code snippets to show how you'd use both projects' APIs to access USB devices.
