adb logcat hangs with “waiting for device” message

Question

When I type adb devices command on terminal, it shows device is connected

List of devices attached

0123456789ABCDEF device

But when I type adb logcat command, it hangs with below message

waiting for device

Can anybody tell me what is the problem behind this? I test the device on cts.

Answer 1

Here is yet another potential method to solve this -- in the past, the above solutions will work, but in my case, this time, this was the thing that fixed it:

1. Plug device into USB
2. Settings -> Developer Options
3. Revoke USB Debugging Authorization
4. Unplug Device
5. Repeat Step 1
6. Authorize Device
7. Repeat Steps 4&5

adb devices should now show device

adb logcat should now output logs from device
