Spreadtrum (Vendor ID 1782) Issues Connecting To Adb

I have a phone which is detected by adb on a Mac, but not on my machine. By 'not detected', I mean that it does show up in lsusb, but 'adb devices' reports a blank list of devices

Solution 1:

Solved, with this universal rule, thanks to this extremely helpful answer:

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

ADB not detecting device samsung i777 in ubuntu 12.04

Thanks to @alex-p

Additional Info:

Phone = Blu Dash Jr

EDIT I also needed to manually add the vendor ID (1782) to the ~/.android/adb_usb.ini file, as follows:

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

Still not sure where the vendor ID list is supposed to be edited since the file tells me not to, but this works.
