CDC驱动在win11下无法识别，看了微软的描述修改子类后正常 (#6783) 这是微软关于此问题的链接: https://learn.microsoft.com/zh-cn/windows-hardware/drivers/usbcon/usb-driver-installation-based-on-compatible-ids#usbsersys-installation Windows 10 及更高版本 从 Windows 10 开始，Usbser.inf 已添加到 %Systemroot%\INF 目录，该目录加载 Usbser.sys 作为设备堆栈中功能设备对象 (FDO) 。 如果设备属于通信和 CDC 控制设备类， Usbser.sys 加载。 无需编写自己的 INF 来引用驱动程序。 驱动程序是基于与包含在 Windows 中的其他 USB 设备类驱动程序相似的兼容 ID 匹配来加载的。 USB\Class_02 USB\Class_02&SubClass_02 如果要自动 加载Usbser.sys， 在设备描述符中将类代码设置为 02，将子类代码 设置为 02。 有关详细信息，请参阅 USB 通信设备类。 使用此方法时，无需为设备分发 INF 文件，因为系统使用的是 Usbser.inf。 如果设备指定类代码 02，但子类代码值不是 02，则 Usbser.sys不会自动加载 。 即插即用管理器尝试查找驱动程序。 如果找不到合适的驱动程序，则设备可能未加载驱动程序。 在这种情况下，你可能需要加载自己的驱动程序或编写引用另一个内置驱动程序的 INF。

2013-08-19ringbuffer: fix the ambiguous nameGrissiom
RT_RINGBUFFER_SIZE could mean "the size of the whole buffer", "the size of the empty space" or "the size of the data". Moreover, it's never a micro anymore. Change it to rt_ringbuffer_data_len before it's too late. Also, RT_RINGBUFFER_EMPTY is changed to rt_ringbuffer_space_len.

2013-05-12cdc_vcom: not to start sending data when the data is already sendingGrissiom
We start the sending transaction in SOF handler. But if the data is already sending, start an other transaction will cause data lose. Implement a state machine is cdc_vcom and avoid that.

This commit set the buffer for packet to CDC_MaxPacketSize which is a reasonable value for it. However, maybe we should make CDC_{RX,TX}_BUFSIZE configurable as well.
