Hi,
I have a revision A imac which has been giving me the following problems.I saved my document with a usb key and know this currently comes up after waking it from sleep. A USB device is currently drawing too much power.The hub it is attached to will be deactivated.I done the proper procedure of quitting my app and then throwing it in the trash.Hoever i have 5 dialogue boxes with that error message which do not want to close.

Also attached is some of the system log
