Studio Manager for DM2000/02R96—Installation Guide
4 Troubleshooting
Cannot control the DM2000/02R96 via USB
• Have you installed the Yamaha USB MIDI driver (Windows page 5, Mac page 13)?
• Is the USB cable connected correctly (page 4)?
• Is the DM2000/02R96 configured correctly (page 4)?
• Is Studio Manager set to the correct ID? (see the Studio Manager documentation)
• Macintosh: Is OMS configured correctly (page 14)? On some systems, the included OMS
studio setup files may not work correctly. In this case, you must create a new studio setup.
See the “OMS_2.3_Mac.pdf” for more information.
Cannot install the Yamaha USB MIDI Driver
• Is the USB cable connected correctly (page 4)?
• Try disconnecting the USB cable, and then reconnecting it.
• Windows: Is USB enabled? When the DM2000/02R96 is connected to your computer for
the first time, if the Add New Hardware Wizard doesn’t appear, it may be because your com-
puter’s USB controller is disabled. To check this, open the System control panel, click the
Device Manager tab, and check for any crosses (x) or exclamation marks (!) next to the
“Universal Serial Bus controllers” and “USB Root Hub” items. If these items do have these
marks next to them, your USB controller is disabled. For information on enabling your USB
controller, refer to your computer’s documentation.
• Windows: If for some reason installation of the Yamaha USB Driver fails, the
DM2000/02R96 may be registered as an unknown device and you may not be able to rein-
stall 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 recon-
nect it, and now try installing the driver again.
OMS stops working after installing the Yamaha USB MIDI Driver
• Macintosh: The Yamaha USB MIDI Driver supports Mac OS 8.6 through 9.2.2. If you install
it on a computer that is running an earlier version of the Mac OS, OMS will not work cor-
rectly. In this case you should remove the Yamaha USB MIDI Driver as explained below.
How to remove & reinstall the Yamaha USB MIDI Driver
• Windows 98/Me: Presuming that the Yamaha USB MIDI Driver was installed successfully,
and that the DM2000/02R96 has been recognized correctly, the driver can be removed from
your computer as follows. Open the System control panel, click the Device Manager tab,
select the “YAMAHA USB MIDI Driver,” and then click the Remove button. After deleting
the following files, disconnect the USB cable, reconnect it, and then reinstall the driver
again.
Windows\Inf\Other\YAMAHADM2000.INF (or YAMAHA02R96.INF)
Windows\System\Xgusb.drv
Windows\System\Ymidusb.sys
• Macintosh: The driver can be removed from your computer by deleting the following files,
after which you should restart your computer, reinstall the driver, and then set up OMS.
