How can I re-install USB Root Hubs?
Apparently, I don't know how (probably someone in my family un-installed all of my USB Root Hubs). I have 1-2 left, and I tried using every single port to connect my mouse and keyboard. They didn't work. I have 2 left, and I really need to connect it urgently.. I'm planning to hook my computer on my TV, and I need this urgently, please help me, how do I fix this problem? Will a system restore be required?
