Using hardware devices with Android SDK in Linux

I had some issues configuring a cheap cell phone, but after a deep searching along every forum and trying all kind of methods proposed I found a good and effective solution.

Cell phone model: BLU Star JR
Vendor ID 1782
Recognized in the Linux OS as Spreadtrum Communications Inc.

I added this universal rule in the /etc/udev/rules.d/51-android.rule

ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:ff420?:*", MODE="0666"

 And manually added the Vendor ID (1782) to the  ~/.android/adb_usb.ini  file

# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x1782

 After that I used the command to assign permission rules

sudo chmod a+r /etc/udev/rules.d/51-android.rules

 Reconnect the device and verify thet my device is connected with

adb devices
