Now in its Fifth Edition, USB Complete bridges the gap between the technical specifications and the real world of designing and programming devices that connect over the Universal Serial Bus (USB). Learn how to select a USB speed, device class, and hardware for a design; communicate with devices using Visual C#; use standard host drivers to access devices, including devices that perform vendor-defined tasks; save power with USB's built-in power-conserving protocols; and create robust designs using testing and debugging tools. This fully revised edition also covers SuperSpeed and SuperSpeedPlus (USB 3.1), wireless options, and USB

读取usb设备文件并上传(问题解决)
前言 有一个需求:Android
otg
连接usb设备(一个带SD卡的可穿戴相机),并读取其内存中的文件上传到网络 ###问题 这个需求最大的难点在于读取usb设备中的文件,并且由于我们上传的API接口要求是以
File
为参数上传文件。而Android提供的是很低级别的API,以bulk
transfer
的方式来传输数据字节流的。 ###知识要点
OTG
On the Go ,主要用于usb和不同的移动设备之间的连接和数据交换,就是用于连接类似手机等移动设备和USB设备的。 文件系统类型 常见的文件系统类型有
