stm32103VB tinyusb使用异常，无法识别描述符是为什么？

问答对人有帮助，内容完整，我也想知道答案 0 尝试STM32F103VB上使用tinyusb，完成配置之后开始没有反应。调试后发现这个上拉电阻的实现需要手动实现控制： dcd_disconnectdcd_connect 之后调试发现设备还是无法识别：之后打开TinyUSB的调试日志 #define CFG_TUSB_DEBUG 3 之后上电出现调试信息： msh >USBD Bus Reset : Full Speed USBD Bus Reset : Full Speed USBD Setup Received 80 06 00 01 00 00 40 00 Get Descriptor Device Queue EP 80 with 18 bytes ...
