Tiny6410的USB HUB不好用是怎么回事儿？

自己用这个Tiny6410核心板照着厂家的原理图扩展出了usb hub 这个设备，板子启动时候logfile:老打印这些东西：


hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1

hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2
hub 1-1:1.0: over-current change on port 1
hub 1-1:1.0: over-current change on port 2

大家帮看看是不是焊的时候哪里出问题了？
