First off, have you tested ANY other USB devices? A corded USB mouse maybe, a USB flash drive, ANYTHING that will tell you whether the ports are indeed working or not.
And if they're not, call up HP, or even take it back to the store you bought it from and ask for a replacement.
So I just bought a new laptop (less than 3 days ago) and was enjoying it today (it is rather great) when my usb wireless mouse refused to respond. I was unconcerned at first, until I replaced the batteries and found that it still didn't work. After reinstalling the drivers, it still didn't work.
So, I've come to the conclusion that it's not the mouse's fault, but rather the usb ports'. I've uninstalled all the usb port drivers as well in Device Manager, and subsequently restarted and reinstalled the drivers - no dice.
Can anyone help me? It's a brand new laptop and I don't want to have to trade it in so soon. Any help appreciated.
