• Is "Unknown Device" displayed for "Other devices" or "Universal Serial Bus
controllers"?
Use the following procedure to delete "Unknown Device" from "Other devices" (Universal
serial bus controller), and re-start your computer.
1. In the Windows Control Panel, double-click System to open the System Properties
dialog box. The System Properties dialog box will appear.
2. Click the Device Manager tab.
3. Double-click Other devices (Universal Serial Bus controllers) to see the list of devices.
4. From the list, select the unknown device and click Delete.
* In order to check whether or not the "Unknown Device" is the UA-3FX, disconnect the USB
cable of the UA-3FX, and verify that "Unknown Device" has disappeared. Then connect the
UA-3FX once again, and delete "Unknown Device."
5. In the Confirm Device Removal dialog box, click [OK].
6. Verify that "Other device" or "Unknown device" is not displayed in the list, and click
[Close] to close the dialog box.
7. Re-start your computer.
The "Add New Hardware Wizard" dialog box appears even
though you installed the drivers
If your computer or USB hub has two or more USB connectors, connecting the UA-3FX to a
USB connector to which the UA-3FX has never before been connected may cause the Add
New Hardware Wizard dialog box will appear even though the drivers have already been
installed.
Install the drivers once again as described in "Getting Connected and Installing Drivers
(Windows)" (p. 14). This is not a malfunction.
The UA-3FX Driver Is Not Installed Correctly.
Use the procedure described in "Deleting the special driver" (p. 70) to delete the USB
Audio Device driver installed in your computer, and install the UA-3FX drivers once again
as described in "Getting Connected and Installing Drivers (Windows)" (p. 14).
Check whether there is an item named "Unknown Device" in "Other devices" or in
"Universal Serial Bus controllers." If you find "Unknown Device," delete it.
