HI3518A+RT3070(WIFI)问题

按照网上诸贤的方法编译，出现如下问题：
# insmod rt3070sta.ko
rtusb init rt2870 --->

不停地输出。

跟踪程序，发现问题出现在这里：
do {
     RTUSB_CONTROL_MSG(pObj->pUsb_Dev, 0, Request, RequestType, Value, Index, pAd->UsbVendorReqBuf, TransferBufferLength, CONTROL_TIMEOUT_JIFFIES, RET);
     if (RET < 0) {
           DBGPRINT(RT_DEBUG_OFF, ("#\n"));
           if (RET == RTMP_USB_CONTROL_MSG_ENODEV)
           {                                       
        RTMP_SET_FLAG(pAd, fRTMP_ADAPTER_NIC_NOT_EXIST);                        break;                                
           }
           RetryCount++;
           RTMPusecDelay(5000); /* wait for 5ms*/
      }
} while((RET < 0) && (RetryCount < MAX_VENDOR_REQ_RETRY_COUNT));
好象是与USB<--->RT3070通迅失常，问题出在RTUSB_CONTROL_MSG上，不知何解？
