Today I started getting the "The last USB device you connected to this computer malfunctioned, and Windows does not recognize it" message. People have reported this happening to pen drives when first plugged in, but this is different.
I was using my graphics tablet, and it had been plugged in for some time when I heard the USB disconnect, then connect noises and then the message popped up, and my tablet would no longer work. At first I thought it was something wrong with my graphics tablet, but then I discovered my mouse started acting weird too and when I reconnected it, it stopped working entirely.
When I unplug or plug things back in, there is no longer a sound or indication that the computer responded to it. It's like the USB system has shut down entirely. The light on my tablet flashes on, indicating that it has power. Restarting the computer fixes the problem, but then it happens again an hour or so later.
My computer is running Windows 8.1 64-bit and it is an HP 15-r210dx. It's brand new, I've only had it for a couple months.
