 在学习 USB 或者是学习 CherryUSB 代码之前，我们需要先基于现有的 demo 进行快速验证，为什么？是为了提升对 USB 的兴趣，能有信心进行下一步的动作，如果 demo 都跑不起来，或者自己摸索写代码，或者先看 USB 基本概念，结果看到最后，
 发现一点都看不懂，概念好多，根本记不住，从而丧失对 USB 的兴趣。因此，先跑 demo 非常重要。下面我将给大家罗列目前支持的 demo 仓库。

+- **dwc2 halt 中不能清除 USB_OTG_HCCHAR_EPDIR，reset port 中使用超时机制，防止在枚举时由于拔出而造成死等**

+- musb 对于标准的 IP 结构采用独立 EP 控制寄存器组，不使用 EPIDX 寄存器去控制
+- 删除所有 CONFIG_USBDEV_EP_NUM & CONFIG_USBHOST_PIPE_NUM，不再使用，因为 IP 本身会携带这些信息，或者厂家 SDK 提供了对应的宏
+- CONFIG_USBHOST_MAX_INTF_ALTSETTINGS 默认使用 2 减少内存，只有 UVC 和UAC 使用（商业收费），所以不需要开很大

 <h1>基于现有 demo 快速验证<a class="headerlink" href="#demo" title="Link to this heading"></a></h1>
 <p>在学习 USB 或者是学习 CherryUSB 代码之前，我们需要先基于现有的 demo 进行快速验证，为什么？是为了提升对 USB 的兴趣，能有信心进行下一步的动作，如果 demo 都跑不起来，或者自己摸索写代码，或者先看 USB 基本概念，结果看到最后，
 发现一点都看不懂，概念好多，根本记不住，从而丧失对 USB 的兴趣。因此，先跑 demo 非常重要。下面我将给大家罗列目前支持的 demo 仓库。</p>

+<ul class="simple">
+<li><p>对 1.5.1 下 rt-thread 组件的一些 bugfix</p></li>
+<li><p>idf timer osal 替换为 esp timer，freertos timer会有启动失败的可能性；xTaskCreate 使用 xTaskCreatePinnedToCore 替换，方便多核使用</p></li>
+<li><p>主机枚举中，删除描述符溢出相关的 ASSERT 操作，改成返回错误。获取字符串描述符改成支持才获取。2 ms 延时改成 10ms，因为一些 os 使用的是 100hz，会造成延时失效</p></li>
+<li><p><strong>dwc2 ep mult 支持，split 传输代码优化，对 split 相关的 cache 处理修改</strong></p></li>
+<li><p><strong>dwc2 halt 中不能清除 USB_OTG_HCCHAR_EPDIR，reset port 中使用超时机制，防止在枚举时由于拔出而造成死等</strong></p></li>
+<li><p>更新 DWC2 中 at32，stm32，kendryte，espressif glue 代码</p></li>
+<li><p>musb 对于标准的 IP 结构采用独立 EP 控制寄存器组，不使用 EPIDX 寄存器去控制</p></li>
+<li><p>删除所有 CONFIG_USBDEV_EP_NUM &amp; CONFIG_USBHOST_PIPE_NUM，不再使用，因为 IP 本身会携带这些信息，或者厂家 SDK 提供了对应的宏</p></li>
+<li><p>CONFIG_USBHOST_MAX_INTF_ALTSETTINGS 默认使用 2 减少内存，只有 UVC 和UAC 使用（商业收费），所以不需要开很大</p></li>
+<li><p>urb interval 从 u8 改 u32，最大支持 2^15 * 125us</p></li>
