Can't connect an already booted device to adb Every time I want to connect my phone to adb via USB I need to turn it off, plug the cable and turn it back on.

Is this the right way to go or am I missing something?

Documentation doesn't seem to explicitly state that.

Some details:


Samsung GT-B5510 Galaxy Y Pro (Android 2.3.6)
Android Debug Bridge version 1.0.29
Debian GNU/Linux 7.0 (wheezy)
I have had similar trouble with a different device.  After you plug you device in try:

adb devices


If your phone is not listed, try restarting ADB:

adb kill-server
adb start-server


Lastly, check if there are any driver updates for your phone.  A good place to start looking for drivers is Google's OEM page and Samsung's support page.  Additional tips might be found on this SO question.
