I have a relatively new HP laptop running Windows 7.
I went on a week's annual leave last week and I came back to discover that my wireless keyboard and mouse weren't responding, and even my spare wired mouse was failing to light up. I tried several other devices and I kept getting a message telling me that the USB device wasn't being detected, and the troubleshooting didn't help.
It seems that the USBs have decided to "die" on me, although it's very strange because although they don't light up the mouse I can still charge my iphone from them.
Any suggestions as to what I can try? And Yes, I have restarted several times!
