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 [ 1938.980000] scsi9 : usb-storage 1-1.2:1.1 [ 1939.000000] usb 1-1.2: MAC-Address: 0x0c:0x5b:0x8f:0x27:0x9a:0x64 [ 1939.010000] cdc_ncm 1-1.2:1.2: wwan0: register 'cdc_ncm' at usb-ehci-platform-1.2, Mobile Broadband Network Device, 0c:5b:8f:27:9a:64 [ 1939.980000] scsi 9:0:0:0: CD-ROM HUAWEI Mass storage ffff PQ: 0 ANSI: 2 [ 1939.990000] scsi 9:0:0:0: Attached scsi generic sg0 type 5 [ 1939.990000] scsi 9:0:0:1: Direct-Access HUAWEI Mass storage ffff PQ: 0 ANSI: 2 [ 1940.000000] sd 9:0:0:1: Attached scsi generic sg1 type 0 [ 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: Jan 1 00:51:24 Pineapple daemon.notice pppd[24955]: pppd 2.4.5 started by root, uid 0 Jan 1 00:51:25 Pineapple local2.info chat[24971]: abort on (BUSY) Jan 1 00:51:25 Pineapple local2.info chat[24971]: abort on (NO CARRIER) Jan 1 00:51:25 Pineapple local2.info chat[24971]: abort on (ERROR) Jan 1 00:51:25 Pineapple local2.info chat[24971]: report (CONNECT) Jan 1 00:51:25 Pineapple local2.info chat[24971]: timeout set to 10 seconds Jan 1 00:51:25 Pineapple local2.info chat[24971]: send (AT&F^M) Jan 1 00:51:25 Pineapple local2.info chat[24971]: expect (OK) Jan 1 00:51:25 Pineapple local2.info chat[24971]: AT&F^M^M Jan 1 00:51:25 Pineapple local2.info chat[24971]: OK Jan 1 00:51:25 Pineapple local2.info chat[24971]: -- got it Jan 1 00:51:25 Pineapple local2.info chat[24971]: send (ATE1^M) Jan 1 00:51:25 Pineapple local2.info chat[24971]: expect (OK) Jan 1 00:51:25 Pineapple local2.info chat[24971]: ^M Jan 1 00:51:29 Pineapple local2.info chat[24971]: ATE1^M^M Jan 1 00:51:29 Pineapple local2.info chat[24971]: ^BOOT:478988,0,0,0,99^M Jan 1 00:51:30 Pineapple local2.info chat[24971]: ^M Jan 1 00:51:30 Pineapple local2.info chat[24971]: ^RSSI:10^M Jan 1 00:51:30 Pineapple local2.info chat[24971]: ^M Jan 1 00:51:30 Pineapple local2.info chat[24971]: ^CSNR:-93,-7^M Jan 1 00:51:33 Pineapple local2.info chat[24971]: ^M Jan 1 00:51:33 Pineapple local2.info chat[24971]: ^RSSI:10^M Jan 1 00:51:33 Pineapple local2.info chat[24971]: ^M Jan 1 00:51:33 Pineapple local2.info chat[24971]: ^CSNR:-96,-10^M Jan 1 00:51:35 Pineapple local2.info chat[24971]: alarm Jan 1 00:51:35 Pineapple local2.info chat[24971]: Failed Jan 1 00:51:35 Pineapple daemon.err pppd[24955]: Connect script failed Jan 1 00:51:36 Pineapple daemon.info pppd[24955]: Exit.
