You are a desktop support technician for your company. All client computers run Windows XP Professional and Microsoft Office XP. A user in your company is attempting to connect a new USB keyboard to his computer. The computer has two USB ports, and both ports are being used by other devices.
The user reports that he cannot connect the USB keyboard to his computer. You verify that the computer’s available ports are a parallel port, a serial port, and two PS/2 ports. You need to ensure that the user can use the new keyboard and the two existing USB devices. Your solution must minimize additional hardware expense.
What should you instruct the user to do?
A.
Obtain a USB-to-PS/2 adapter. Attach the keyboard to an open PS/2 port by using the adapter
B.
Obtain a serial port version of one of the two existing USB devices. Then connect that device to the open serial port to free up a USB port for the keyboard.
C.
Obtain a self-powered USB hub. Connect all three USB devices to the hub. Then connect the hub to the
computer.
D.
Obtain a bus-powered USB hub. Connect all three USB devices to the hub. Then connect the hub to the computer.
