I have an Aspire E1 laptop, and for some reason the usb ports are behaving strangely. They'll give output for any device I've tried so far (i.e. charging my phone), but they'll only take input from some. For example, I can use a usb drive completely normally, as well as a mouse, but I can't use my pen-tablet, or my printer. The computer doesn't even register that they're connected. This started suddenly with nothing out-of-the-ordinary happening to the computer to prompt it. Any ideas what the problem could be, or how I could go about fixing it?
