您好！
我的am3352设备将两个USB控制器都配置为HOST模式，进入linux系统后插入U盘能够正常识别挂载读写，插入一个usb转串口设备也可以识别，但是插入一个无线网卡就会打印如下信息：
# [ 2094.370288] usb 1-1: new high-speed USB device number 7 using musb-hdrc
[ 2094.490289] usb 1-1: device descriptor read/64, error -71

[ 2096.170294] hub 1-0:1.0: unable to enumerate USB device on port 1
另外一个USB口接一个4G模组，也同样打印上述信息。请问该如何解决？是硬件问题还是驱动问题？
我使用的是linux-3.12.10-ti2013.12.01
非常感谢！
