powered hub "freaking out" the 'puter?
Got a funny problem and I'm looking for a little advice on how to handle it.
First off, I'm using a dell optiplex gx270. I've got a powered hub in the front dash (running off a small 1000ma power supply, basically an ipod usb car charger) for the for the dash mounted dvd drive.
Here's the problem:
When I start the car, it seems power is feeding back through the hub to the puter and it looks as if the puter is going into a "hibernation" state (power button pulses orange). When I get the main power up and running (ie: car started or into acc), I have to shut the computer down by holding the power button for 5 secs and then everything will start as normal.
If I unplug the hub, everything works fine. I've noticed that if I "unplug" the puters main power, my radioshark is still lit up and seems as if I am drawing power from the front hub through the puter usb ports and back out to the radioshark.
Sorry if the description is a little confusing, but this is baffleing me a bit.
Anyone have any idea what's happening here and what to do about it?
Is there a "power on with usb" setting I'm missing or something similar?
