Question

adb devices was working fine last year, but after upgrades and new software installs, adb devices no longer recognizes USB attached Android devices.

Answer 1

I just ran into this problem using my HTC Inspire (Android 2.3.3) and Mac OS 10.6.8.  The phone did not enter USB debugging mode when I connected it to my USB hub, but it did start USB debugging mode when I connected it directly to my MacBook Pro.

... and then, of course, it showed up in the list of devices attached.
