ADB not detecting device samsung i777 in ubuntu 12.04

问题

this is the first time I am trying to setup adb to connect s2 with my ubuntu desktop. However, when I run adb devices and/or adb usb it cannot detect the s2. I have followed the following steps:

1. create udev rules
2. add to ~/.android/adb_usb.ini

But the device is not getting connected while I am in the download/odin mode.

My system is Ubuntu 12.04 64-bit and I am using the adb pre-packaged with android studio running lsusb shows me the following output:

Bus 002 Device 004: ID 04e8:685d Samsung Electronics Co., Ltd

I have also added the following line to my /etc/udev/rules.d/51-android.rules :

# Samsung Galaxy I777
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04e8", MODE="0666", GROUP="plugdev"

and for the sake of full disclosure the permissions are:

-rwxr-xr-x 1 root root   95 Jun  2 17:16 51-android.rules

also the ~/.android/adb_usb.ini has the line0x04e8

回答1:

Try this universal udev rule, which matches all adb and fastboot interfaces regardless of vendor ID:

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