在用户使用说明书上说中兴AC581是验证过的，但是我买了个中兴AC581不能正常使用：
中兴AC581在PC上可以正常使用，插到mini2440上打印信息如下：
usb 1-1: new full speed USB device using s3c2410-ohci and

usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

打开友善的3G拨号上网程序，可以识别到 ZTE AC581(CDMA),但是点击“ok”之后的“connect”，打印信息如下：
usb 1-1: usbfs: process 986 (3g-modem) did not claim interface 0 before use

最后是Disconnected，失败！
各位大神，如何解？？
