Problems Related to the USB Driver (Windows)

Problem
When I start (or restart) my
computer with the V-Synth
connected via USB, it freezes
at the startup screen and fails
to work
When I turned off the power of
the V-Synth, an error oc-
curred in Windows
When I attempt to exit Win-
dows while leaving the V-
Synth powered up, the com-
puter does not turn off
When I connect the V-Synth
via USB and wake up my com-
puter from Suspend, it stops
functioning
V-Synth drive is not mounted
in Windows XP
"Find new hardware wizard"

cally
The "Insert Disk" dialog box
does not appear
"Find new hardware wizard"
ends before the process is
completed
* It may take about 15 seconds
(or more) after the USB cable
is connected for the V-Synth
to be detected.
"Found unknown device" ap-
pears even though you in-
stalled the driver
Cause
Is the instrument set to receive Exclusive messages?
Does the Device ID number of the transmitting device
match the Device ID number of the V-Synth?
audio interface is fixed at 44.1 kHz, regardless of the
System mode setting. Noise may be heard from con-
nected devices at this time.
Could you have selected a preset wave?
The Power-up Mode is set to "Default."
Cause
It has been found that on some computers, starting (or
restarting) the computer while the V-Synth is powered
up and USB is connected will cause the computer to
freeze at the startup screen and fail to work.
When using Windows Me, powering down the V-
Synth without unmounting the drive may cause an er-
ror to occur in Windows.
On some Windows computers, it has been reported
that the computer cannot be powered down if you exit
Windows when the V-Synth is still powered up (with-
out unmounting the drive). (The shutdown process
halts before the computer's power is switched off.)
On some computers, waking up the computer from the
Suspend state while a powered-up V-Synth is connect-
ed via USB will cause the computer to freeze.
If a network drive is mounted in Windows XP, that
drive number may conflict with the V-Synth drive,
causing the V-Synth drive to not be recognized.
Is the USB cable connected correctly?
Is USB enabled on your computer?
Does your computer meet the USB specifications?
If your computer or USB hub has two or more USB con-
nectors, and you connect the V-Synth to a USB connec-
tor to which the V-Synth has never been connected
before, the "Unknown device" dialog box may appear
even on a computer onto which you have already in-
stalled the driver.
Troubleshooting
Action
Set the Rx Sys-Ex parameter to ON (p. 124).
Check the Device ID parameter setting (p. 123).
This is not a malfunction.
The V-Synth's factory-loaded preset waves cannot be
edited or encoded. Select a sample that you've sampled
or imported.
Change it to "Last Set" and save the System settings (p.
122).
Action
Switch off the V-Synth and then restart your computer.
You must cancel the USB connection (p. 140) before
you turn off the power of the V-Synth.
You must cancel the USB connection (p. 140) before
you turn off the power of the V-Synth before you exit
Windows.
Before you Suspend your computer, power down the
V-Synth using the procedure described on p. 140.
Change the assignment of the network drive.
Make sure that the V-Synth and your computer are cor-
rectly connected via a USB cable.
Refer to the operation manual for your computer, and
make sure that USB is enabled.
If you are using a computer that does not fulfill the
electrical requirements of the USB specifications, oper-
ation may be unstable. In this case, you may be able to
solve the problem by connecting a USB hub.
If the above actions do not solve the problem, it is pos-
sible that the V-Synth has been incorrectly detected by
the computer. As described in "Deleting Incorrect De-
vice Information" (p. 196), delete the incorrect device
information, then re-install the driver.
Refer to Readme file on the included CD-ROM, and in-
stall the driver once again. This is not a malfunction.
If the "Found unknown device" dialog box appears
even though the V-Synth is connected to the same USB
connector as before, it is possible that the computer has
detected the V-Synth incorrectly. As described in "De-
leting Incorrect Device Information" (p. 196), delete
the incorrect device information, then re-install the
driver.
