usb hub with a manual switch (i have one device overriding other)

greetings, I have a client using two dictation softwares that require two different mics. One mic (basic usb) mic takes over and automatically becomes the default making the other mic useless. They wont go through the trouble of disabling the mic in the hardware manager each time they want to use it. there is a switch on the usb mic itself but only shuts the mike off. it keeps the driver loaded. Im looking for a usb hub with a switch so they could just hit the button to disable/enable the port on the hub with the usb mic. Do they exist and do you have any other ideas? thanks in advance.
