Android: Phone isn't recognized by ADT after upgrading

Question

I just upgraded to the latest Android SDK (r16) and Eclipse (3.7.2). Now I can not use USB devices. I can connect the phone to my Mac (Lion) and share data but the "adb devices" returns an empty list (only emulators are displayed).

Yes.. I have "Unknown sources" and "USB debugging" turned on. I have 3 Android devices and none of them work (but they did before upgrade).

Does anyone has a fix?

UPDATE: Can someone please test this?

try adb kill-server to force a restart. – yorkw Feb 29 '12 at 08:47 — yorkw, Feb 29 '12 at 08:47
@yorkw Do you have the latest configuration? – xpepermint Feb 29 '12 at 08:54 — xpepermint, Feb 29 '12 at 08:54

Just check whether the below options are checked:

settings->Applications->Unknown Sources
settings->Applications->Development->USB debugging

I am sure but these two may be restored as default.

Nope... as I wrote I have these things on. – xpepermint Feb 29 '12 at 08:48
then "adb kill-server" may be a solution. – Paresh Mayani Feb 29 '12 at 08:51

Maybe try adb plugin? Use "adb kill-server" and "adb start-server" and check devices. I have got same problem and it works.

first make sure the device development usb debugging open,

and then you can using:

adb kill-server

adb devices

to refresh devices list

These are answers I've read on the other sites but no... it does not fix my problem. Do you have the latest configuration? – xpepermint Feb 29 '12 at 08:51
try this: when usb connected, you close usb debugging and reopen again, and then invoke above shell command. – idiottiger Feb 29 '12 at 09:03
Nope... would you be so kind and test this on the latest configuration? – xpepermint Feb 29 '12 at 09:08
