3G上网卡识别问题
我在friendArm的2440， 识别不出一款3G上网终端的老版本（ 新版本能够识别）,dmesg的信息如下（不停重复）

请问下这个的解决思路?
兄弟，你是不是也在调试ET302？ 我这边也有一块，调试不出来。TD的资料太少了，也不知道是什么个驱动原理 我在Ubuntu上debug了一下，发现这款3G卡的驱动类型是CDC-MLDM，现在正准备开启GADGET宏编译一下，看能否用这个驱动来支持该卡，大家有什么进展吗？ #HUAWEI ET302 12d1:1d50
你试试：
usb_modeswitch -I -W -D -s 20 -v 0x12d1 -p 0x1d50 -u 2
这样串口的设备节点就出来了。

这位兄弟，我现在就是切换配置文件没问题，但是这卡的驱动就是挂不到节点上去。

关键是这张卡不知道为什么一个驱动都没有加载成功，内核是2.6.31的，我今天看见usb/class/cdc_acm到3.3版本经过了很多次修改。不知道是否新内核是否支持该卡。
