usb_modeswitch转换模式 出错

你好，我最近在做华为ET128的3G驱动，网上说第一次插进开发板时是被认作CD-ROM  所以就要转换成MODEOM模式 所以我移植了usblib usb_modeswitch工具，信息如下：

我就是想问下found USB ID 0100:0201这个ID是啥啊 我没有这个ID的USB设备啊 他读的啥啊 （我用usb_modeswitch.c是1.1.2版本的)
希望研究过和做过这方面东西的高手指点下
补充：我将3G网卡拿掉，没有硬件时，信息如下（还是有个ID）：

上面的问题不要看了 是我移植的东西有问题 以解决  关键是有出新问题啦

我到哪一步之后再没反映啦 想请问下是啥原因啊

我通过打印信息测试得知是如下过程出错：
在usb_modeswitch.c中的ret = usb_bulk_write(devh, MessageEndpoint, (char *)command, 31, 0);和ret = usb_bulk_read(devh, ResponseEndpoint, data, 36, 0);我的程序走过了usb_bulk_write，却在usb_bulk_read中进入了死循环。。。。。然后我在移植的libusb库中找到了int usb_bulk_write(usb_dev_handle *dev, int ep, char *bytes, int size,
        int timeout)
{
  /* Ensure the endpoint address is correct */
  return usb_urb_transfer(dev, ep, USB_URB_TYPE_BULK, bytes, size,
                timeout);
}

int usb_bulk_read(usb_dev_handle *dev, int ep, char *bytes, int size,
        int timeout)
{
  /* Ensure the endpoint address is correct */
  ep |= USB_ENDPOINT_IN;
  return usb_urb_transfer(dev, ep, USB_URB_TYPE_BULK, bytes, size,
                timeout);
}

/*然后通过打印信息知道是在usb_urb_transfer中的    while (!urb.usercontext && ((ret = ioctl(dev->fd, IOCTL_USB_REAPURBNDELAY, &context)) == -1) && waiting) {
      tv.tv_sec = 0;
      tv.tv_usec = 1000; // 1 msec
      select(dev->fd + 1, NULL, &writefds, NULL, &tv); //sub second wait
  }   usb_bulk_write执行一次就退出来拉  而usb_bulk_read确实无限循环  网上有 人说是卡里没钱啦 但这段代码和卡里有没有钱好像没关系啊

根据你的描述，好像还没有到拨号哦，现在还只是在找设备。应该是驱动方面没有驱动好导致的。

楼主在吗？？？我现在也在移植这个，你具体步骤怎么做啊？

我出现这样的错误。。。。。楼主帮我看看 谢谢！！！具体步骤告诉我行不？

我现在想移植 3G上网卡 到RQ2440  具体怎么做啊！！！！！有人做过吗？？
