Connect Firefox OS Spreadtrum devices through adb

The ultra low-cost Firefox OS devices to be launched in India are built on Spreadtrum chipsets. Here are the quick steps for people running Linux or OS X to connect their Spreadtrum devices through adb:

Make sure if the device is detected

• Connect the device through a USB cable.

• Enable Remote Debugging on the device from the Developer menu.

• Run lsusb on Linux and ensure that the device is detected. the output of lsusb will have a line like this:

  $ lsusb
…
Bus 003 Device 008: ID 1782:5d04 Spreadtrum Communications Inc.
…


Here, 1782 is the vendor ID and 5d04 is the product ID. If you don’t see your device in this output, make sure you’ve enabled Remote Debugging and the USB cable or the device itself is not faulty.

Note: OSX users can use lsusb for OSX.

Create udev rule:

• Edit (or create) /etc/udev/rules.d/51-android.rules and add:

  SUBSYSTEM==“usb”, ATTRS{idVendor}==“1782”, MODE=“0666”


• Restart udev. On Linux, do this:

  # /etc/init.d/udev restart


Add vendor ID to adb_usb.ini

• Edit (or create) ~/.android/adb_usb.ini and add this on a new line:

  0x1782


• Ensure that this line is not repeated in the adb_usb.ini file.

Restart adb server and reconnect the device

• Kill adb server

  $ adb kill-server


• Connect the device through USB cable.

• Search for devices through adb. This will respawn the adb server.

  $ adb devices


If everything is in place, the device should show up in the List of devices attached in the output.
