Under Ubuntu 12.04, the ADB command does not display the device ID

1. Add the ADB command to/usr/local/bin. Command:

sudo cp ~/working/ics/out/host/linux-x86/bin/adb/usr/local/bin/

2. Create the file 50-android.rules. Command:

sudo vim/etc/udev/rules.d/99-android.rules (99 for permissions, if there are two such to a file, execute the permission high. Input

subsystem== "USB", attrs{idvendor}== "1782", attrs{idproduct}== "5d24", mode= "0666", owner= "Raulyang"

Where device Idvendor can be viewed through LSUSB:

Bus 001 Device 016:id 1782:5d04 Spreadtrum Communications Inc.

3. Execution command: chmod a+rx/etc/udev/rules.d/99-android.rules

4. In the home directory, create the. Android directory, new Adb_usb.ini file in the. Android directory, add the value of Idvendor, enter: 0x1782 save to exit.

Fortunately, ADB, in addition to a built-in list, there is a Adb_usb.ini file to maintain a trusted list of third-party vendors, need to vid (Vender ID) written to adb_usb.ini

5. Restart: Sudo/etc/init.d/udev restart

6. Execute: sudo adb kill-server
