Problems related to the USB driver

• When the USB cable is connected or disconnected, approximately 15 seconds (or more) may be required for the UA-3 to be recog-
nized.
• Is the USB cable connected correctly?
Make sure that the UA-3 and computer are connected correctly by the USB cable.
• Can USB be used on your computer?
Refer to the owner's manual for your computer, and make sure that it is able to use USB.
• Does your computer or USB hub have sufficient power supply capacity?
The UA-3 cannot be connected if insufficient power is supplied to it. Check whether one of the following cases apply.
If you are using the UA-3 with a notebook computer that is running on its battery, operation may be unreliable with some models of com-
puter. If this is the case, connect the AC adaptor to your notebook computer.
The power conservation mode of your computer may limit the power that is supplied to USB. Check the settings of your computer.
In some cases, the UA-3 cannot be used with a bus-powered hub (a hub that does not contain a power supply). Please use a self-powered
hub (a hub that contains a power supply).
• Does your computer meet the USB specifications?
If you are using a computer that does not meet the USB specifications (such as a homemade computer), operation may be unstable. In
such cases, you may be able to solve the problem by connecting a USB hub that contains a power supply.
• 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.
2. Click the [Device Manager] tab.
3. Double-click [Other devices] (Universal Serial Bus controllers) to see the list of devices.
4. In the list, select Unknown Device and click [Remove].
5. In the Confirm Device Removal dialog box, click [OK].
6. Make sure that the list does not show Other devices or Unknown Device, and click [Close] to close the dialog box.
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-3 to a USB connector to which the UA-3 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 Connections and driver installation (Windows) (p. 8). This is not a malfunction.
UA-3
In order to check whether or not the "Unknown Device" is the UA-3, disconnect the USB cable
of the UA-3, and verify that "Unknown Device" has disappeared. Then connect the UA-3 once
again, and delete "Unknown Device."
