Description: The good news is you don’t even need to bother reading the entire USB standard. Some chapters were churned
out by marketing, others aimed at the lower link layer normally taken care off by your USB controller IC and a
couple aimed at host and hub developers. Lets take a little journey through the various chapters of the USB 2.0
specification and briefly introduce the key points Platform: |

Description: 此代码是遍历pc上usb设备。
包含控制器 hub port 设配id 等信息
usb其实和串口是一样的，其端口也是固定的（如果你不接扩展hub）。
有时一台电脑接多个相同的usb设备，如果接连个摄像头（前后各一个），我们如果区分打开的是哪一个呢？
1、先把usb设备先遍历出来，得到usb信息（设备串等）。
2、通过打开usb设备时返回信息（这个很重要 //usb#vid_1d27&pid_0600#5&10ef021e&0&5#{c3b5f022-5a42-1980-1909-ea72095601b1}）。
3、遍历注册表得到usb设备信息（#define USB_REGPATH "SYSTEM\\CurrentControlSet\\Enum\\USB\\" ）。
4、通过第1条的设备串、第2条打开设备返回信息、注册表。就可以确定usb设备(控制器->hub->端口)
-This code is to traverse the PC USB device.
Includes a controller hub port with ID and other information
USB actually and serial port is the same, the port is fixed (if you don t pick up the extension hub).
Sometimes a computer connected to a plurality of the same USB device, if have a camera (before and after each one), if we distinguish open is which one?
1, the first USB device first traversal, get the USB information (such as equipment series).
2, through the information returned when opening the USB device (this is very important for //usb#vid_1d27&pid_0600#5&10ef021e&0&5#{c3b5f022-5a42-1980-1909-ea72095601b1}).
3, traversing registry USB device information (USB_REGPATH "#define SYSTEM\\CurrentControlSet\\Enum\\USB\\").
4, through the equipment first series, second open the device returns information, registry.You can determine the USB (controller->hub-> port)

Description: CH374是一个USB总线的通用接口芯片，支持USB-HOST主机方式和USB-DEVICE/SLAVE设备方式，内置3端口HUB根集线器，支持低速和全速的控制传输、批量传输、中断传输以及同步/等时传输。在本地端，CH374具有8位数据总线和读、写、片选控制线以及中断输出，可以方便地挂接到单片机/DSP/MCU/MPU等控制器的系统总线上。除此之外，CH374还提供了节约I/O引脚的SPI串行通讯方式，通过3线或者4线SPI串行接口以及中断输出与单片机/DSP/MCU/MPU等相连接。(CH374 is a universal interface chip for USB bus, supports USB-HOST host mode and USB-DEVICE / SLAVE device mode, built-in 3-port HUB root hub, supports low-speed and full-speed control transmission, batch transmission, interrupt transmission, and synchronization / isochronous transmission. At the local end, CH374 has an 8-bit data bus and read, write, chip select control lines, and interrupt output, which can be easily connected to the system bus of a microcontroller / DSP / MCU / MPU controller. In addition, CH374 also provides a SPI serial communication method that saves I / O pins. It is connected to a single-chip computer / DSP / MCU / MPU through a 3- or 4-wire SPI serial interface and interrupt output.) Platform: |
