My computer stopped recognizing 2 devices plugged in. It will see other devices plugged into the same ports, but not those 2. The devices work on another computer, my laptop running Zorin, so I know its not a problem with them.
I don't know if somehow it was something I did. I have my computer hooked up to my TV in my room, and often fall asleep with my keyboard still on my bed. I woke up, and there was a message saying that I needed to restart for the changes to take place, I hadn't made any changes that I was aware of. I restarted anyhow, and ever since then, my external hard drive, and thumb drive that were plugged in at the time are no longer working properly when plugged into this computer.
