TUSB8041: TUSB8041高温(50℃)及高温高湿(40℃/湿度95%)时,数据收发错误

Part Number: TUSB8041

TI的专家:

          我在使用TUSB8041制作一款USB HUB控制板,在高温环境(50℃)时,USB3 TEST PLUG接在HUB板的3.0下行端口,HUB板的上行端口接在工控机上,用USB回环工具测试USB HUB板收发数据的功能;发现有掉线的情况

        同时,TUSB8041下端级联TUSB4041扩展4个USB2.0接口,发现USB 2.0的下行接口在高温(50℃)也会掉线;并且级联的TUSB4041扩展4个USB2.0接口在高温高湿(40℃/湿度95%)时,也有掉线情况,请问一下TI的专家,两个问题该怎么解决?
