Macintosh users

Case 1: An error dialog box is displayed

Is the UM-2 driver installed?
An error dialog box will be displayed if the UM-2 is
connected to your computer before the UM-2 driver is
installed.
If the display indicates " The software needed to use the
USB device "Unknown Device" cannot be found. Please
refer to the device documentation to install the necessary
software ", click "OK."
If the display indicates " Software needed for the USB
device "Unnamed Device" is not available. Would you like
to look for the software on the Internet? ", click "Cancel."
After closing the dialog box, follow the procedure for " Using
OMS on the Macintosh" (P.27) or " Using FreeMIDI on the
Macintosh" (P.31) to install the UM-2 driver.
Case 2: Cannot install the USB MIDI driver
Did you exit all other programs?
Exit all currently-running programs.
Case 3: Cannot make USB connections correctly
Was the UM-2 recognized?
Disconnect the USB cable, and then re-connect it.
If another USB device is connected, try connecting only the
UM-2.
It is possible that the computer did not correctly recognize or
initialize the UM-2. Leave the USB cable connected to the
UM-2, and restart your Macintosh. If the connection is still not
achieved, exit your Macintosh and turn off the power of the
computer. Then turn on the power of the computer once
again, and start up your Macintosh.
The computer cannot recognize the UM-2 when the USB
connector of Macintosh's keyboard is used. Re-connect the
USB cable to the USB connector of the main body.
Are your computer or USB hub (*) supplying sufficient
current?
If insufficient current is being supplied to the UM-2,
connection is not possible.
• Use a USB hub which contains its own power
supply.
• The power conservation mode settings of your
computer may be limiting the current supplied to
the USB, so check these settings.
Troubleshooting
For details on the electrical
current that can be
supplied by your
computer or USB hub refer
to the owner's manual for
your equipment. If you
have questions, please
contact the manufacturer
or dealer for your
computer or USB hub.
The UM-2 cannot be used
with a hub that contains no
power supply.
