[已解决]HG556a(brcm63xx)刷openwrt后无法连3g网卡

jbcdi***

用的是移动的TDS的网卡,之所以不用cdma或更高的3g,是因为不想开太多的流量套餐,自己的移动卡自己克隆过,所以手机和网卡共用一个流量套餐.

以前在703n上配置过,OK的,没问题,能识别成ttyACM0-2,然后自动拨号.然后买了个HG556a,刷的是官方的12.09版的openwrt-HG556a_128k-squashfs-cfe.bin,在http://wiki.openwrt.org/toh/huawei/hg556a?s=hg556a上下载的固件.

在/dev下也能看到ttyACM0,ttyACM1,ttyACM2,按理来说,应该是识别出来并识别成modem了.logread后的日志:

/etc/config/network里也添加了:
config 'interface' '3g'
option 'auto' '1'
option 'proto' '3g'
option 'device' '/dev/ttyACM0'
option 'service' 'umts'

上述配置在703n里是可行的.

但是现在就是死活不会拨号,即使执行ifup 3g,在logread里没有任何反应,就是根本没有执行拨号命令.有没有哪位大神帮忙看看啊.

另外,用chipgenius查下来这卡是24AE:2000,但是openwrt是用12d1:1da1来识别的,不知道有没有问题?

那么多天,都没有高手来帮忙吗?

通过大量对比,总算知道为啥不能自动拨号了.因为缺少kmod-ppp和ppp的安装包,我操!

但是拨号后连不上,日志是:

然后无线循环...有谁知道为啥吗?

问题原因总算找到了.

3个USB口,3G网卡必须插在那个被塑料盖子保护的口上才行.看了下日志,侧面的USB口是1-1.1,黄色LAN口旁的USB口是1-1.2,被塑料盖子保护的USB口是2-2,明显前两个是接在USB hub上的,而第三个是直接连USB芯片的.问题在于,为啥连了hub,就没法3G拨号了?
