I have a fairly new Lenovo Y510p laptop (only about 3 weeks old). I have had a wireless keyboard and mouse combo hooked up to one of the two USB ports on the left side of the machine. Today, the computer fails to recognize anything plugged into these two usb ports. There is one usb port on the other side of the laptop (right side) that works just fine. I've spent the past few hours trying to troubleshoot the problem to no avail. The laptop seems to vent heat very well and I have not noticed anything else to indicate overheating. Here's a list of the things I have tried, with no success:
-Uninstall USB root hub in the device manager and reboot
-Update the chipset drivers
-Multiple system reboots
-Uninstall and reinstall the drivers for the mouse/keyboard combo (its a Logitech Wireless Wave Combo MK550)
-Try different usb devices in the two non working slots (including a wired keyboard and an external wifi adapter)
I really hope that this is not a hardware problem, but it wouldn't surprise me if it was. If anyone has any ideas on what else I can try, it would be much appreciated. Thanks!
