I am sending this question here, even though it relates to a couple of iMacs, as in reality it's USB which is the subject and not iMac.
I have just seemingly killed (?) two Bondi iMacs by plugging a powered USB hub in.
Prior to using the hub, they both worked fine, now they won't start up at all. I can hear the click of the PSU when I plug in the power cable, but even pressing the button on the front with nothing else plugged in, nothing happens.
It's a TopCom USB 2.0 (1.1 compatible) powered hub with 4 ports, so nothing out of the ordinary but I am 100% sure that it was the hub that caused the fault(s).
1. What could have happened to the iMacs ?
A shorted out USB hub fried the logic board via the USB ports.
Can they be fixed ?
If the above happened, yes...with a new Mobo.
Any checks to be made ?
From your description of the problem, I'm wagering that a decent funeral and wake, followed by resurrection as MacQuaria is in order.
2. Is it likely to be a faulty hub, or is there some incompatibility (though there shouldn't be) ?
Likely it's a killer hub. Give it to an enemy with a Windows system.
