The USB-MIDI Driver cannot be installed.
• Is the USB cable connected correctly?
• Is the USB function enabled on your computer?

the USB function on the computer may be disabled.
Perform the following steps.
1
Select [Start]
→
[Control Panel] (

[System]
→
[Hardware])
→
[Device Manager].
The “Device Manager” window appears.
2
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]

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.
