Issues with Huawei E587 modem


Recommended Posts

I guys, I have a Huawei E587 modem which is not supported out of the box (as it seems) by the MKV, I'm following this guide, so my steps were:
- Install cdc_ncm package.
opkg -nodeps install http://galapago.sakura.ne.jp/openwrt/12_09_rc1/kmod-usb-net-cdc-ncm_3.3.8-1_ar71xx.ipk

- Install modeswitch's parameter file for E587

cd /etc/usbmodeswitch.d
wget -O 12d1:1c1b http://galapago.sakura.ne.jp/openwrt/12_09_rc1/12d1_1c1b

Now when I plug the device to the usb port, I see the following dmesg:

[ 1938.820000] usb 1-1.2: new high-speed USB device number 14 using ehci-platform
[ 1938.970000] option 1-1.2:1.0: GSM modem (1-port) converter detected
[ 1938.970000] usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB0

[ 1940.030000] sd 9:0:0:1: [sda] Attached SCSI removable disk

( The cd-rom stuff it's normal, the device has a built in partition with softwares for windows ).

So far so good, if I execute ifconfig -a I see the interface with the right mac address:

wwan0     Link encap:Ethernet  HWaddr 0C:5B:8F:27:9A:64  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
Now, since the protocol ncm is not in the list of the mobile configuration web ui, if I try to put it as a custom protocol nothing happens ( pppd is not launched basically ), if I try other configs such as:
config interface 'wan2'
        option proto '3g'
        option device '/dev/ttyUSB0'
        option service 'umts'
        option apn 'MY_APN'
        option username 'MY_USERNAME'
        option password 'MY_PASSWORD'
        option defaultroute '1'

I get the following (error) logs from pppd:
