Windows 7: Laptop USB ports acting strangely, can't figure out why

Laptop USB ports acting strangely, can't figure out why

I was just browsing the net with the usual plugged into my laptop (external in the lefthand port, keyboard and mouse in the righthand ports) when suddenly my keyboard and mouse just stopped working. The external on the left is fine and is still functioning as I type this.

The mouse didn't show any signs of life when plugged into other ports but the keyboard had all three of the lock lights glowing. I tried restarting my laptop, uninstalling the USB hubs in Device Manager, making sure power management doesn't turn them off and still they wouldn't work.

After one restart my keyboard would work if the mouse wasn't plugged in, as soon as you did that the keyboard would either show all three lock lights or no lights at all. At one point they both worked together but after about five second of moving the mouse both stopped responding again.

It got to the point where if I moved my mouse a lot the lights on the keyboard and mouse would flash for a second. After doing this a few times in frustration I got a message about USB Hub power surges and to click here to deal with the problem. I was too slow with the trackpad so I missed clicking. I can only find XP related information on these and haven't got another so I'm kinda stuck.

In summary: the USB ports on the righthand side of my laptop stopped working without any hardware or software changes, there could have been some sort of power surge and sometimes my keyboard works.

USB Hub power surges
I suggest you get an externally powered USB HUB. Seems like your USB system can't supply the power needed anymore.
