用的是am3517处理器,是北京瑞泰(TI的代理商)的ICETEK-AM3517-KB-EZ。关于usb接鼠标要接个HUB才能用,而不能直接在USB接口直接插鼠标。而想周立功的开发板上的鼠标不需要接HUB,可以直接接在USB口上使用。如果直接接鼠标,提示错误:
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
hub 1-0:1.0: Cannot enable port 1. Maybe the USB cable is bad?
hub 1-0:1.0: unable to enumerate USB device on port 1

您说的周立功的开发板也是AM3517的?请问您的鼠标是否是经过USB 认证过的鼠标?
