Bus 001 Device 008: ID 058f:6366 Alcor Micro Corp. Android Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Find the corresponding line for your android phone.
The Vendor & Product ID will be in XXXX:XXXX format. In our example the ID's is 058f:6366 .
058f = VendorID.
6366 = ProductID.
Create Rules.

sudo gedit /etc/udev/rules.d/51-android.rules
you can use vi, nano, pico or any text editor in place of gedit.

append the code to the file.
SUBSYSTEM=="usb", ATTR{idVendor}=="058f", ATTR{idProduct}=="6366", MODE="0666", GROUP="plugdev"
Create adb file in home ( ~ ) folder.

mkdir ~/.android
( if not already created. )

touch ~/.android/adb_usb.ini

echo '0x6366' >> ~/.android/adb_usb.ini
Restart udev.

sudo service udev restart

adb kill-server

adb start-server
Reconnect the Phone.
You may need to disconnect and reconnect the phone again. and wait for a couple of minute to get it detected.
adb devices

# The short way.

Copy this code into the terminal (replaces id's) and run it.


echo 'SUBSYSTEM=="usb", ATTR{idVendor}=="6366", ATTR{idProduct}=="058f", MODE="0666", GROUP="plugdev"' | sudo tee -a /etc/udev/rules.d/51-android.rules && mkdir ~/.android/ && touch ~/.android/adb_usb.ini && echo '0x6366' >> ~/.android/adb_usb.ini && sudo service udev restart && adb kill-server && adb start-server && adb devices

Replace the VendorID & ProductID with the one you got....

the short way

Short tutorial for those who donot have all the time in the world to read a lengthy tutorial.
Open ' Terminal ' and run..


eject /dev/sr1

Bus 001 Device 004: ID 24e3:3e76 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Note the ID corresponding to USB/3G Modem.


sudo modprobe usbserial vendor=0x24e3 product=0x3e76

the long way

This tutorial will work for most 2G, 3G, 4G or any USB Modem under GNU/Linux using debian/ubuntu.

# Before inserting your usb modem. Open 'Terminal' and run the following command:


ls /dev/sr*

It'll output something like:


/dev/sr0

sr0 is mostly CD/DVD-Drive or any Serial Drive connected.

# Now insert your USB Modem and run the command again..


ls /dev/sr*


/dev/sr0 /dev/sr1

Note the extra serial device (sr1). it is your usb modem internal storage, because when attached they are dectcted as storage devices. It's explained in 'man usb_modeswitch'.


...When plugged in for the first time, they  act like  a  flash  storage  and  start  installing the Windows driver from there. If the driver is already installed, it makes the storage device disappear  and  a  new device, mainly composite with modem ports, shows up.



On Linux, in most cases the drivers are available  as  kernel  modules, such  as "usbserial" or "option". However, the device shows up as "usb-storage" by default...

# In 'Terminal':

Bus 001 Device 004: ID 24e3:2205 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

note the ID corresponding your USB 3G Modem.

# Eject the modem storage:


eject /dev/sr1

..and..


lsusb


Bus 001 Device 004: ID 24e3:3e76 3G Modem 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It will show a new ID for the Modem.
24e3:3e76
24e3 is VendorID. 3e76 is ProductID of the modem.

# Make the modem visible to the system by running modprobe:


sudo modprobe usbserial vendor=0x24e3 product=0x3e76

Replace the ID with your Modem ID.

Wait a minute for the modem to appear in Network Manager.
