使用了端点0、1、2枚举正常 *((u16 *)(PMAAddr)) = 0x0080;//(u16)ENDP0_TXADDR; *((u16 *)(PMAAddr+2*2)) = 0x0000; *((u16 *)(PMAAddr+4*2)) = 0x0040;//(u16)ENDP0_RXADDR; *((u16 *)(PMAAddr+6*2)) = 0x8400; *((u16 *)(PMAAddr+16)) = 0x00d0;//(u16)ENDP1_TXADDR; *((u16 *)(PMAAddr+16+2*2)) = 0x0000; *((u16 *)(PMAAddr+16+4*2)) = 0x00c0;//(u16)ENDP1_RXADDR; *((u16 *)(PMAAddr+16+6*2)) = 0x8000; *((u16 *)(PMAAddr+32)) = 0x00f0;//(u16)ENDP2_TXADDR; *((u16 *)(PMAAddr+32+2*2)) = 0x0000; *((u16 *)(PMAAddr+32+4*2)) = 0x00e0;//(u16)ENDP2_RXADDR; *((u16 *)(PMAAddr+32+6*2)) = 0x8000; 请用过的讲讲各个端点4个u16的数据都是什么意思 |

不是给电脑发的描述符什么的是在STM32 USB缓冲区头几个字节的端点描述表。
谢谢，最后移植官方库了。
