RT73 USB无线网卡无法在linux下正常工作

各位大虾，请教一个问题：
      小弟在OK6410板子上做无线传输实验，买了块RT2571 USB无线网卡，驱动装上后插入无线网卡，开始还能工作，一两分钟之后就出现以下错误：
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 1 - CWmin: 4, CWmax: 10, A
ifs: 2, TXop: 0.
phy1 -> rt2x00mac_conf_tx: Info - Configured TX queue 2 - CWmin: 4, CWmax: 10, A

hub 1-0:1.0: unable to enumerate USB device on port 1
....
之后有自动识别网卡，然后工作一会儿，又出错、unable to enumerate USB device on port 1一直循环往复，我的烦死了也不知道怎么回事，求各位大虾指点。谢谢！
PS：我的usb host接口是usb1.1标准的

小弟，我也出现过。我的是RT3070,装好驱动后，一插上USB就出现如下：
usb 1-1: device descriptor read/64, error -71
usb 1-1: device descriptor read/64, error -71
Not CMD_RUN!!
usb 1-1: new low speed USB device using FOTG2XX_DRV and address 3

usb 1-1: new low speed USB device using FOTG2XX_DRV and address 5

好像是什么描述符的问题。
求解。
