The YAMAHA USB-MIDI Driver cannot be installed.
• Is the USB cable connected correctly?
Refer to the DME64N/24N Owner's Manual to confirm proper
connection of USB cables.
• Is the USB function enabled on your computer?
When you connect the DME 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.
1
Select [Start] → [Settings] → [Control Panel] → [System].
The "System" window appears.
2
Double-click the "Device Manager" tab and make sure
that no "!" or "x" marks appear at "Universal serial bus
controller" or "USB Root Hub."
If you see the "!" or "x" mark, the USB controller is
disabled. Refer to the owner's manual of your computer for
details.
• Is any unknown device registered?
If driver installation fails, the DME will be shown as an
"Unknown device," and you will not be able to install the
driver. Delete the "Unknown device" by following the steps
below.
1
Select [Start] → [Settings] → [Control Panel] → [System].
The "System" window appears.
2
Double-click the "Device Manager" tab. With the "View
devices by type" check box checked, look for "Other
devices."
3
If you find "Other devices," double-click it to extend the
tree to look for "Unknown device." If one appears, select it
and click the [Remove] button.
4
Remove the USB cable from the DME, and make the
connection again.
5
Install the driver again according to the instructions
following step 4 on page 3.
When controlling the DME from your computer via
USB, the DME does not operate correctly.
• Did you install the driver?
• Is the USB cable connected correctly?
• Is the YAMAHA USB-MIDI Driver set up appropriately?
• Have you selected an appropriate port in the DME
Designer or another relevant MIDI application?
Make sure that the settings in one application have either the
combination of "YAMAHA USB IN 0-1" and "YAMAHA USB
OUT 0-1," or the combination of "YAMAHA USB IN 0-2" and
"YAMAHA USB OUT 0-2."
Settings combining different port numbers (i.e., "YAMAHA
USB IN 0-1" and "YAMAHA USB OUT 0-2," or "YAMAHA USB
IN 0-2" and "YAMAHA USB OUT 0-1") cannot be used.
• Have you selected the same USB ports in both the DME
Designer and another relevant MIDI application?
Change the setting of the USB port so that both the DME
Designer and the other MIDI application match.
Troubleshooting
• Are you using the latest YAMAHA USB-MIDI driver?
The latest driver can be downloaded from the Yamaha
website (address given at the end of this manual).
• Have you selected USB as MIDI port in the DME?
Select USB for the MIDI port.
• Did you launch DME Designer after connecting a USB
cable and turning the device ON?
Be sure to connect the USB cable and turn the device on
before launching DME Designer.
• Was the USB cable disconnected during operation?
If the USB cable is accidentally disconnected, DME designer
will not recognize the device even if the cable is reconnected.
You will have to restart DME Designer.
When controlling the DME from your computer via
Ethernet, the DME does not operate correctly.
• Did you install the driver?
• Is the Ethernet cable connected correctly?

Select [Start] → [Settings] → [Control Panel] → [Network
Connections] → [Local Area Connection], and confirm the
network setup.
• Are the settings of DME and peripheral network devices
(including switching hubs) appropriate?
Refer to the relevant owner's manuals for the DME and
peripheral network devices (including switching hubs) for
details.

Designer?

• Do not suspend the computer while the DME Designer 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 DME functions again.)
