I have a Lenovo Twist computer/laptop running windows 8
I had a crazy USB issue. I had 4 USB devices plugged in. Hub, attached to printer keyboard and printer and a camera in the other USB port.
Always works fine in this config and suddenly I set it up and the hub connected components won't work and Windows says the USB device malfunctioned.
I tried a different hub and same thing, restarted everything....
Then tried unplugging laptop and running on battery power and everything went back to normal. But plugged into the wall the messages come back..... I happened to have another ac adpter and tried that and no plroblems....
My question is how is the AC adapter causing problems? Any ideas?
