In my experience that message has usually occurred because of a device that really should have its own power supply or in this case the cable. A couple of questions occur to me though:

!. Do the problems persist after you restart the Mac? That usually clears it up form me. The problem may well return if you plug in the device that started the problem.

2. If the problem goes away and only occurs with the droid connected does the droid have a separate power cord. With my old Palm phone it would sometimes cause this unless I charged it via the external power cord.

Do a reboot and run Repair Permissions and as Sly suggests, get a main powered USB hub.

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
