It has three USB 2.0-compliant connectors and one D/Bay external media bay connector. > If it has 2, try plugging each into the machine directly. I don't know what you mean by this.

I've never had it crash when plugging in a USB device, and this crash seems to happen right before it wants to give me the login prompt, so it seems like if it were truly a power issue I'd have problems in these circumstances. Let me know if there's any more info I can provide. Thanks, Mike
