D-Link HSPDA Dongle - DWN-156

會先出現 cd rom，然後要切 modeswitch，才會出現 serial port。
在 windows 上會出現三個 serial port (其中一個是 USB Modem):

1. D-Link HSPDA DataCard Diagnostics Interface
3. D-Link HSPDA DataCard NMEA Device
4. D-Link HSPDA DataCard Propertiery USB Modem

這又是一個 有 usb cdrom 模式的 3g dongle。
剛插入系統，會是 cd rom。
要先 switch 到 modem 後，才會出現 usb serial。

剛插入時，vid , pid 是：

New USB device found, idVendor=07d1, idProduct=a804

mount 再 umount 後，vid, pid 是：

New USB device found, idVendor=07d1, idProduct=7e11

但是這時後也沒有出現 usb serial port。

大概用兩個步驟：

1. usb-modeswitch, 切換到 modem mode
2. 手動 load usb-serial ，指定 vid, pid

usb-modeswitch:

debian 已經有安裝，但是 /etc/usb_modeswitch.d/ 下面沒有 07d1:a804 的設定檔，
所以要寫 /etc/usb_modeswitch.d/ 下的 vid:pid 檔：
sudo vi /etc/usb_modeswitch.d/07d1:a804 ######################################################## # D-Link DWM-156 HSUPA 3.75G USB Modem DefaultVendor= 0x07d1 DefaultProduct=0xa804 TargetVendor= 0x07d1 TargetProduct= 0x7e11 MessageContent="5553424312345678000000000000061b000000020000000000000000000000" CheckSuccess=20 寫好就可以用 usb_modeswitch 來切了..

先插入 dwn-156, dmesg 內容是： [25387.281621] usb 2-1.1.4.2: new high speed USB device using ehci_hcd and address 19 [25387.391940] usb 2-1.1.4.2: New USB device found, idVendor=07d1, idProduct=a804 [25387.391946] usb 2-1.1.4.2: New USB device strings: Mfr=3, Product=2, SerialNumber=4 [25387.391950] usb 2-1.1.4.2: Product: D-Link WCDMA Technologies MSM [25387.391954] usb 2-1.1.4.2: Manufacturer: D-Link,Incorporated [25387.391957] usb 2-1.1.4.2: SerialNumber: MF112DDLKD010000 [25387.392114] usb 2-1.1.4.2: configuration #1 chosen from 1 choice [25387.394534] scsi16 : SCSI emulation for USB Mass Storage devices [25387.394655] usb-storage: device found at 19 [25387.394659] usb-storage: waiting for device to settle before scanning [25392.392130] usb-storage: device scan complete [25392.392810] scsi 16:0:0:0: CD-ROM HSPA USB SCSI CD-ROM 2.31 PQ: 0 ANSI: 2 [25392.397282] sr1: scsi-1 drive [25392.397481] sr 16:0:0:0: Attached scsi CD-ROM sr1 [25392.397632] sr 16:0:0:0: Attached scsi generic sg4 type 5 用 usb_modeswitch 來切換 mode: $ sudo usb_modeswitch -c /etc/usb_modeswitch.d/07d1:a804 Looking for target devices ...

看一下 dmesg: [38715.226573] usb 2-1.1.4.2: new high speed USB device using ehci_hcd and address 23 [38715.337316] usb 2-1.1.4.2: New USB device found, idVendor=07d1, idProduct=7e11 [38715.337321] usb 2-1.1.4.2: New USB device strings: Mfr=3, Product=2, SerialNumber=4 [38715.337324] usb 2-1.1.4.2: Product: D-Link WCDMA Technologies MSM [38715.337327] usb 2-1.1.4.2: Manufacturer: D-Link,Incorporated [38715.337329] usb 2-1.1.4.2: SerialNumber: MF112DDLKD010000 [38715.337460] usb 2-1.1.4.2: configuration #1 chosen from 1 choice
已經切換了。

然後動 load usb-serial module，指定 vid,pid sudo modprobe usbserial vendor=0x07d1 product=0x7e11
dmesg 可以看到 ttyUSB 出現： [38715.339951] usbserial_generic 2-1.1.4.2:1.0: generic converter detected [38715.340069] usb 2-1.1.4.2: generic converter now attached to ttyUSB0 [38715.340178] usbserial_generic 2-1.1.4.2:1.1: generic converter detected [38715.340280] usb 2-1.1.4.2: generic converter now attached to ttyUSB1 [38715.340537] scsi20 : SCSI emulation for USB Mass Storage devices [38715.340695] usb-storage: device found at 23 [38715.340699] usb-storage: waiting for device to settle before scanning [38715.340788] usbserial_generic 2-1.1.4.2:1.3: generic converter detected [38715.340889] usb 2-1.1.4.2: generic converter now attached to ttyUSB2 [38720.337127] usb-storage: device scan complete

這時候，在 panel 的 network widget 就可以看到 "Chungwha Telecom.."，
打勾 就可以連上了。
