 CherryUSB Device Stack provides a unified framework of functions for standard device requests, CLASS requests, VENDOR requests and custom special requests. The object-oriented and chained approach allows the user to quickly get started with composite devices without having to worry about the underlying logic. At the same time, a standard dcd porting interface has been standardised for adapting different USB IPs to achieve ip-oriented programming.

 ## Host Stack Overview
 
-The CherryUSB Host Stack has a standard enumeration implementation for devices mounted on roothubs and external hubs, and a standard interface for different Classes to indicate what the Class driver needs to do after enumeration and after disconnection. A standard hcd porting interface has also been standardised for adapting different USB IPs for IP-oriented programming. Finally, the host stack is managed using os, and provides osal to make a adaptation for different os.

 ## Host 协议栈简介
 
-CherryUSB Host 协议栈对挂载在 roothub、外部 hub 上的设备规范了一套标准的枚举实现，对不同的 Class 类也规范了一套标准接口，用来指示在枚举后和断开连接后该 Class 驱动需要做的事情。同时，规范了一套标准的 hcd porting 接口，用于适配不同的 USB IP，达到面向 IP 编程。最后，协议栈使用 OS 管理，并提供了 osal 用来适配不同的 os。

 - 自动加载支持的Class 驱动
 - 支持阻塞式传输和异步传输
 - 支持复合设备
-- 支持多级 HUB,最高可拓展到 7 级(目前测试 1拖 10 没有问题，当前仅支持 dwc2 和 ehci)
-- 支持 Communication Device Class (CDC_ACM, CDC_ECM)
+- 支持多级 HUB，最高可拓展到 7 级(目前测试 1拖 10 没有问题，仅支持 dwc2/ehci/xhci/rp2040)
+- 支持 Communication Device Class (CDC_ACM, CDC_ECM, CDC_NCM)
 - 支持 Human Interface Device (HID)
 - 支持 Mass Storage Class (MSC)
-- Support USB Video CLASS（商业收费）
-- Support USB Audio CLASS（商业收费）
+- Support USB Video CLASS (UVC1.0、UVC1.5)
+- Support USB Audio CLASS (UAC1.0)
 - 支持 Remote NDIS (RNDIS)
 - 支持 USB Bluetooth (支持 nimble and zephyr bluetooth 协议栈，支持 **CLASS: 0xE0** 或者厂家自定义类，类似于 cdc acm 功能)
-- 支持 Vendor 类 class
+- 支持 Vendor Serial 类(CH34X、CP210X、PL2303、FTDI、GSM)
+- 支持 Vendor network 类(RTL8152、AX88772)
 - 支持 USB modeswitch
+- 支持 Android Open Accessory
 - 支持相同 USB IP 的多主机
 
 同时，CherryUSB Host 协议栈还提供了 lsusb 的功能，借助 shell 插件可以查看所有挂载设备的信息，包括外部 hub 上的设备的信息。

+ * wIndex:         Port
+ * wLength:        0
+ * Data:           None
+ * The BaudDivisor values are calculated as follows:
+ * - BaseClock is either 12000000 or 48000000 depending on the device.
+ *   FIXME: I wish I knew how to detect old chips to select proper base clock!
+ * - BaudDivisor is a fixed point number encoded in a funny way.
+ *   (--WRONG WAY OF THINKING--)
+ *   BaudDivisor is a fixed point number encoded with following bit weighs:
+ *   (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
+ *   end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
+ *   (--THE REALITY--)
+ *   The both-bits-set has quite different meaning from 0.75 - the chip
+ *   designers have decided it to mean 0.125 instead of 0.75.
+ *   This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
+ *   and Flow Control Consideration for USB to RS232".
+ * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
+ *   automagically re-encode the resulting value to take fractions into
+ *   consideration.
+ * As all values are integers, some bit twiddling is in order:
+ *   BaudDivisor = (BaseClock / 16 / BaudRate) |
+ *   (((BaseClock / 2 / BaudRate) & 4) ? 0x4000    // 0.5
+ *    : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000  // 0.25
+ *    : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000  // 0.125
+ *    : 0)
+ *
+ * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
+ * of 0.125 missing from the FT8U232AM.  Bits 16 to 14 are coded as follows
+ * (the first four codes are the same as for the FT8U232AM, where bit 16 is
+ * always 0):
+ *   000 - add .000 to divisor
+ *   001 - add .500 to divisor
+ *   010 - add .250 to divisor
+ *   011 - add .125 to divisor
+ *   100 - add .375 to divisor
+ *   101 - add .625 to divisor
+ *   110 - add .750 to divisor
+ *   111 - add .875 to divisor
+ * Bits 15 to 0 of the 17-bit divisor are placed in the urb value.  Bit 16 is
+ * placed in bit 0 of the urb index.
+ *
+ * Note that there are a couple of special cases to support the highest baud
+ * rates.  If the calculated divisor value is 1, this needs to be replaced with
+ * 0.  Additionally for the FT232BM, if the calculated divisor value is 0x4001
+ * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
+ * not supported by the FT8U232AM).
