ENGLISH
• If for some reason installation of the Yamaha USB Driver fails, the ACU16-C/NHB32-C
may be registered as an unknown device and you may not be able to reinstall the driver until
the unknown device is deleted. In this case, open the System control panel, click the Device
Manager tab, and select the “View devices by connection” option. If an item called “Other
devices” appears in the list, click it. If there’s an item called “Unknown device,” select it and
then click the Remove button. Disconnect the USB cable, then reconnect it, and now try
installing the driver again.

Improving performance
• If your computer seems unresponsive, make sure it satisfies the system requirements
(page 10).
• Quit any other applications that you are not using.
Cannot suspend or resume your computer
• Suspend will not work if there are any MIDI applications open.
• Windows 2000: Depending on the USB controller, etc., on some systems, suspend and
resume may not work properly. If the ACU16-C/NHB32-C stops responding, try discon-
necting and reconnecting the USB cable.
