Troubleshooting
"Found unknown device" appears even though you installed
the driver
If your computer or USB hub has two or more USB connectors, and you connect the UA-700 to a USB
connector to which the UA-700 has never been connected before, the "Unknown device" dialog box
may appear even on a computer onto which you have already installed the driver.
Refer to Getting Connected and Installing Drivers (Windows) (p. 14), and install the driver once
again. This is not a malfunction.

Driver is not installed correctly

As described in Deleting the special driver (p. 251), delete the USB audio device driver that is
installed in your computer, and then install the UA-700 driver once again as described in Getting
Connected and Installing Drivers (Windows) (p. 14). Also check whether there is an "Unknown
device" in "Other devices" or "Universal Serial Bus Controller."
If you find one, delete it.
