Yamaha DME Troubleshooting

DME Setup Manual 17

The USB-MIDI Driver cannot be installed.

• Is the USB cable connected correctly?

• 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.

1Select [Start] → [Control Panel] (→ [System] →

[Hardware]) → [Device Manager].

The “Device Manager” window appears.

2Make 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.

1Select [Start] → [Control Panel] (→ [System] →

[Hardware]) → [Device Manager].

The “Device Manager” window appears.

2Look for “Other devices.”

3If 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.

4Remove the USB cable from the DME, and make the

connection again.

5Install the driver again according to the instructions

described on page 4.

When controlling the DME from your

computer via USB, the DME does not

operate correctly.

• Did you install the USB-MIDI driver?

• Is the USB cable connected correctly?

•Have you selected an appropriate port in the DME

Designer?

Make sure that the settings in the DME Designer have the

combination of “YAMAHA USB IN 0-1” (Yamaha DME

NETWORK-1) and “YAMAHA USB OUT 0-1” (Yamaha DME

NETWORK-1). The combination of “YAMAHA USB IN 0-2”

and “YAMAHA USB OUT 0-2” can also be used for the

DME64N/24N. 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.

• Is the USB-MIDI Driver Thru ON/OFF parameter set

to “OFF”?

Go to [Start] → [Control Panel] → [Yamaha USB-MIDI

Driver] and make sure that the [Thru ON/OFF] parameter is

set to “OFF”.

•Have you selected the same USB ports in both the

DME Designer and another MIDI application?

Change the port setting so that the DME Designer and the

other MIDI applications use different ports.

• Does the number of registered MIDI devices exceed

the Windows limit?

The Windows operating system allows a maximum of 10

MIDI device drivers to be installed and registered. In some

cases changing the USB port to which a device is

connected can cause it to be recognized as a different

device, thereby “artiﬁcially” exceeding the limit. If MIDI

doesn't function properly try uninstalling and then re-

installing the USB-MIDI Driver.

• Are you using the latest USB-MIDI Driver supporting

DME?

The latest driver supporting DME can be downloaded from

the Yamaha website.

• 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.
