If you experience problems, read this chapter first. It contains tips for solving most
problems.
Driver-related problems (Windows)
Can't install the driver correctly
You attempted to install as described in "Installing the driver," but did not
succeed.
Install the UA-25 driver once again as described in "Driver installation and settings
(Windows)" (p. 14). Also check the Device Manager to see whether "Other device,"
"Unknown device," "?," "!," or "x" is shown for any device. If you see such a device,
delete it.
Does the Device Manager show "Other device," "Unknown device," or any
device marked with "?," "!," or "x"?
If driver installation did not end successfully, the installed driver may remain in an
incomplete state.
Install the UA-25 driver once again as described in "Driver installation and settings
(Windows)" (p. 14).
Is the UA-25 connected correctly?
Make sure that you have used a USB cable to correctly connect the UA-25 to the USB
connector of your computer.
Could other USB devices be connected?
When installing, all USB devices other than the UA-25 should be disconnected from
your computer.
If you have connected the UA-25 to an external USB hard disk, please connect the UA-
25 directly to a USB connector on the computer itself.
Could other applications or resident software (such as an anti-virus program)
be running?
Installation may not occur correctly if other programs are running. Be sure to close all
other programs before installing.
Are you attempting to install from a networked CD-ROM drive?
You cannot install from a networked CD-ROM drive.
Could the CD-ROM or the lens of your CD-ROM drive be dirty?
If the CD-ROM or the lens of your CD-ROM drive are dirty, the installer may not work
correctly. Use a commercially available CD cleaner or lens cleaner to clean the CD-ROM
and/or lens.
Are the power conservation settings of your computer turned off?
If power conservation settings are turned on for your computer, disable these settings.
(For details on how to disable them, refer to the owner's manual of your computer.)
