The driver cannot be installed.

• Is the USB function enabled on your computer?

→ When you connect the instrument to the computer for the ﬁrst time,

if the "Add New Hardware Wizard" does not appear, the USB

function on the computer may be disabled. Perform the following

steps.

Windows 98/Me), or select [Control Panel]* → [System] →

[Hardware] → [Device Manager] (for Windows 2000/XP).

2 Make sure that no "!" or "x" marks appear at "Universal serial

bus controller" or "USB Root Hub." If you see an "!" or "x" mark,

the USB controller is disabled.

"Unknown device," and you will not be able to install the driver.

Delete the "Unknown device" by following the steps below.

Windows 98/Me), or select [Control Panel]* → [System] →

[Remove] button.

When controlling the instrument from your computer via USB,

the instrument does not operate correctly or no sound is

heard.

• Did you install the driver?

• Is the USB cable connected correctly?

• Are the volume settings of the instrument, playback device, and

application program set to the appropriate levels?

• Have you selected an appropriate port in the sequence software?

• On the Clavinova, check whether the Piano Lock is engaged or not.

Playback response is delayed.

• Does your computer satisfy the system requirements?

• Is any other application or device driver running?

Cannot suspend or resume the computer correctly.

• Do not suspend the computer while the MIDI application is running.

• If you are using Windows 2000, you may not be able to suspend/resume

normally, depending on the particular environment (USB Host

Controller, etc.). Even so, simply disconnecting and connecting the USB

cable will allow you to use the instrument functions again.
