OpenWrt using 3G Internet card

Thank you so much for taking the time to guide me.
My equipment is db120 mu350 and Guangdong Unlimited Card
Version isOpenWrtBackfire 10.03.336 DIY full

One, not installed to kmod-usb-acm why?



Second, I am in the terminal to start the route, plug the MU350,WINSCP connected to the route, open the terminal input command to see if MU350 has been identified. The display is as follows (unlike what you wrote, my mu350 identified)
/etc/modules.d$ DMESG | grep usb
Usbcore:registered New Interface Driver USBFS
Usbcore:registered New Interface Driver hub
usbcore:registered New device driver USB
Usbcore:registered New Interface Driver rtl8187
Usbcore:registered New Interface Driver P54USB
USB Usb1:configuration #1 chosen from 1 choice
USB Usb2:configuration #1 chosen from 1 choice
USB 2-1: New full speed USB device using BCM63XX_OHCI and address 2
Usbcore:registered New Interface Driver USBLP
Usbcore:registered New Interface Driver usbserial
USB 2-1: Configuration #1 chosen from 1 choice
Usbserial_generic 2-1:1.0:generic Converter Detected
USB 2-1: Generic converter now attached to ttyUSB0
Usbcore:registered New Interface Driver Usbserial_generic
USBSERIAL:USB Serial Driver Core
Usbcore:registered New Interface Driver Usb-storage
Usbcore:registered New Interface Driver ZD1211RW

Third, this step omitted the above is the 3G Internet card recognition. If your 3G card can not turn off the storage mode, it will need to use the Usb-modeswitch, the software before we have installed.
We created the/etc/usb-modeswitch.conf directly, as follows:
[Copy to Clipboard] [ - ]
CODE:
# ZTE MU350
#
# Contributor:dale Lane
Defaultvendor= 0x19d2;
defaultproduct= 0x0003
# Choose one of these:
Detachstorageonly=0
messagecontent=5553424312345678000000000000061b000000020000000000000000000000

Then execute the usb_modeswitch-w, you can switch the MU350 to modem mode.

After using Usb-modeswitch, the device is not necessarily/dev/usb/tts/0 or/dev/ttyusb0, or it may be/dev/usb/tts/1 or/DEV/TTYUSB1

3G NicThe identification of the most important is the creation of/etc/usb-modeswitch.conf, the information of the relevant network card needs to be researched and collected together.
In addition, if Huawei's card usb-modeswitch can not be identified, try installing this package: Huaweiaktbbo
[Copy to Clipboard] [ - ]
CODE:
Opkg Install Huaweiaktbbo

Then run the command directly: Huaweiaktbbo
[Copy to Clipboard] [ - ]
CODE:
Huaweiaktbbo
