Q: USB Over Current Notice - Nothing Connected
Hey all,
so recently i hooked back up my power mac and it worked well for the first couple months.
However, today i was not so lucky. I have a 20 inch apple monitor attached, and it has 2 usb ports. Those ports are almost always plugged in, but when i try to plug them in together, now i get the message 5 times in a row: USB Over Current Notice, A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated.
After playing around with it for over an hour, I've drawn a couple conclusions. If nothing is connected: it will still pop up 5 times in a row. If I have just the keyboard in (and mouse connected to keyboards USB): the message pops up, however the hub (usb on monitor) is not deactivated. If i plug in my music streamer and the keyboard: message pops up and the hub is deactivated.
Finally my troubleshooting.
Resetting the SMU: http://support.apple.com/kb/HT1436
Not sure if this is a late 2004 or late 2005 Power Mac G5, but i did it the 2004 way so far.
Resetting the PRAM: http://support.apple.com/kb/HT1379
Both have not helped the problem, if the problem still exist I will take off the aluminum cover and reset the SMU or PMU or whatever else people suggest within the next couple of days.
Currently on my laptop watching it pop up every 30 seconds between me holding return (closing the 5 windows). ugh
PowerMac, Mac OS X (10.5.8)
