Spreadtrum (Vendor ID 1782) Issues Connecting to a

Question

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:

adb devices List of devices attached

I have tried the following:

• Switching USB Cables
• Ensuring that device is in USB Debug Mode
• Factory resetting the device
• Adding the vendor ID (1782) to /etc/udev/rules.d
• Adding an entry to the ~/.android/adb_usb.ini file (is this necessary?)
• Multiple adb start-server and adb kill-server sequences
• Multiple reboots (and "sudo udevadm control --reload-rules")
• Ran "android update adb", which erases the entry in ~/.android/adb_usb.ini

Pertinent Info:

• Running Ubuntu 14.04
• Entry in lsusb which is added when I plug in the device:

Bus 003 Device 003: ID 1782:5d01 Spreadtrum Communications Inc.

• Line within /etc/udev/rules.d/51-android.rules :

SUBSYSTEM=="usb", ATTR{idVendor}=="1782", MODE="0666", GROUP="plugdev"

I can debug other devices using the same USB port and same cable without an issue, but I'm unsure why this phone won't connect.

Other related issues:

• Android: adb does not recognize phone
• adb devices does not show my device every now and then
• Problem to run my application on a real device

The first link appears similar to this issue, but I don't see any resolution. Does adb consider a list of devices other than what is in the udev rules? Is something else grabbing this device and keeping adb from noticing it?

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"

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.
