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 PCR-1 to a USB
connector to which the PCR-1 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
(p. 14), and install the driver once again. This is not a malfunction.
If the
“Found unknown device”
dialog box appears even though the PCR-1 is connected to the
same USB connector as before, it is possible that the computer has detected the PCR-1 incorrectly.
Please reinstall the driver from the beginning of the procedure (p. 14).
