Hello,
My Toshiba C650 USB port works only when I connect the mouse but stops working when I connect any other devices such as a phone or printer. What is the problem?

    Try refreshing the USB Stack.
    Refresh the USB Stack

    a. Bring up - Device Manager –

    b. Expand USB Serial Controllers - RIGHT CLICK on EVERYTHING and UNINSTALL
    all except the category itself.

    c. REBOOT the computer. This refreshes the drive and the USB stack

    (Additional devices may also be asking for more power than can be provided by the USB hub.)
