Query: Works... as long as you don't turn off computer

I bought this product to share a monitor between two computers. It worked perfectly as long as I left both computers on all the time. If I turned off a computer and then turned it back on, I had to unplug the USB cables and then reinsert them into the computer to get the device to recognize the computer that had been off. Needless to say, I unhooked the device and no longer use it.
