TI的LM3S9B92的USB虚拟串口，用一个串口软件发数据，经常发大数据时就容易挂掉，下面是BUSHOUND抓的数据，各位大大给分析下该怎么解决，源码就是标准TI例程：每次出现GET_COMMSTATUS就再也发不下去了

这以后就一直是GET_COMMSTATUS了

千问 · 2021-1-27 06:30:17

出现GET_COMMSTATUS应该是USB设备没有应答。可以尝试降低传送速度。

引用4楼的回复:出现GET_COMMSTATUS应该是USB设备没有应答。可以尝试降低传送速度。

这个是指波特率么？我现在测试的是，如果下面的波特率是38400，上面的是56000,是效果最好的
