平台：HI3515
内核:LINUX 2.6.24
最近本人在弄usb-WIFI，在板子上插上wifi，板子启动时出现：usb 2-1：device descriptor read/64,error -62 的问题，到网上查了很多资料都说是时钟问题，可是我在插个U盘，U盘可以识别，以下是插了usb-wifi，U盘的打印信息：
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
usb 1-1: new full speed USB device using hi3515v100-ohci and address 2

usb 1-2: new full speed USB device using hi3515v100-ohci and address 6
usb 1-2: configuration #1 chosen from 1 choice

U盘的枚举好像是没问题的，为什么wifi就有问题了？
求高手解答。。。。。。
