Thanks Fred, yes ground looping was one issue when I had a laptop with a bad battery and tried to power from vehicle. How do I determine USB cable shielding quality? Braided, or spun? (spun is more flexible). I have had so much trouble with USB I have 6 or 8 different adapters that I juggle until on...

Coming from a MS background I have had some miserable experiences with noise interfering with USB. I have had to minimize USB cabling and use RS232 to eliminate lockups and other nasty's. I cant even use a USB mouse, must use bluetooth. Is this an Asus Eee PC 900 issue? Or will I see similar issues ...
