Android device not showing up in DDMS

Question

Running Android 2.2 on a Galaxy S. Host is an OS X 10.6.4 machine. DDMS in Eclipse reports no devices being connected. adb devices -- nothing.

I've tried:

1. Rebooting the phone
2. Toggling the USB development mode
3. Plugging/unplugging the cable
4. Restarting the server (adb kill-server).

The weird thing is that sometimes computer will not detect the phone being attached (no growl notification, not syslog entries) and sometimes it will. Other android devices work.

Do you guys have any ideas what else I could try or is this a lost cause?

Thanks

Answer 1

On recent macbook pros, one port will not work consistently. Tested on 2 different Macbook Pros.

Answer 2

Had the same issues with colleagues and found that somehow, "USB Debugging" was disabled in the settings, even though it had worked fine just a few days before.

Just thought I'd mention it because it had us stumped for a bit.
