你好，我一直用的EDUP的USB wifi无线网卡，
连接到板子上的时候老是报：
[ 283.442331] usb 2-1: device descriptor read/64, error -110
[ 298.672800] usb 2-1: device descriptor read/64, error -110
[ 298.903256] usb 2-1: new full speed USB device number 9 using s5p-ohci
[ 309.317329] usb 2-1: device not accepting address 9, error -110
[ 309.442324] usb 2-1: new full speed USB device number 10 using s5p-ohci
[ 319.856403] usb 2-1: device not accepting address 10, error -110
[ 319.856508] hub 2-0:1.0: unable to enumerate USB device on port 1
请问这是什么原因，怎么解决？
我用的最新的android4.0.3的镜像
