I have a Toshiba laptop with 3 USB ports. The ports stopped working, independently, over time. Now I can't use a mouse with the laptop so basically it's a non functional computer for me.
I don't know if this is hardware failure or software/driver failure. It's running Windows 7 and no updates were installed recently.
Which tools can I use to troubleshoot this issue? How do I know if it's a hardware problem? By visual inspection I don't see any damage in the ports. Only a mouse was used in the ports.
