Answer 1

Just stop and start adb server as root. Permissions issue will go away. Also udev step can be skipped.

Answer 2

Maybe adding the vendor ID in ~/.android/adb_usb.ini would help?
Add a line with just 0x<!!!Your Vendor ID here!!!>, then run adb kill-server and adb start-server.

It just saved me after nights of searching/testing/editing/pluging in and out and in again... so I thought it might be worth sharing. Thanks to Uygar Y for his answer.

Answer 3

I am using Ubuntu, what I did is killing and restarting the ADB server with a sudo privilege.

sudo adb kill-server
sudo adb start-server

Answer 4

I'm having the same problem. Strangely, I can sometimes get the device to list correctly, but other times, it just won't work. Restarting my Linux laptop resolves the issue. What a pain!!

Today, I discovered that if I suspend my laptop, then turn it back on, it detects the device correctly again! That really beats restarting the OS.

Answer 5

Try this way, 1.Close Eclipse (IDE) first. 2.Execute this command on terminal " adb kill-server" 3.Now connect device to system wait, 10-20 seconds. 4.Execute this command on terminal " adb start-server", Check device status with "adb devices " command. 5 .Now open eclipse.

Answer 6

If, when you run adb devices, you see ???????????? in the list of devices, try stopping (adb kill-server) and restarting (adb start-server) the adb daemon.

Note that Samsung 04E8 is not a valid entry in 51-android.rules for udev. The correct line is:

SUBSYSTEM=="usb", SYSFS{idVendor}=="04e8", MODE="0666"

Also, make sure that you update the udev daemon after making this rules file change (sudo restart udev).
