实际数: 0x08 0x06 0x00 0x02 0x00 0x00 0x00 0x09
我得出的数据。 0x08 0x06 0x00 0x02 0x00 0x00 0x00(这里为空字符)
开始USB
设备请求
设置地址
设备请求
置配请求。。。0x08 0x06 0x00 0x02 0x00 0x00 0x00 (这里为空字符)
就在这里出错。。读不出长度。。停一会,再重新枚举,
最后还能枚举成功,不明什么原因?我用D11和D12都是一样。。郁闷啊。
reset重起
suspend挂起
reset重起
suspend挂起
suspend挂起
reset重起
设备描述符请求。
设地址
设备描述符请求。
配置描述符。。。()这里没有给出长度。。/。?不明。
