Troubleshooting
• Is USB enabled on your computer?
Refer to the operation manual for your computer, and make sure that USB is enabled.
• Does your computer meet the USB specifications?
If you are using a computer that does not fulfill the electrical requirements of the USB
specifications, operation may be unstable. In this case, you may be able to solve the problem by
connecting a USB hub.
If the above actions do not solve the problem, it is possible that the M-100FX has been incorrectly
detected by the computer. Re-install the driver.

M-100FX to a USB connector to which the M-100FX has never been connected before, the
"Unknown device" dialog box may appear even on a computer onto which you have
already installed the driver.

is not a malfunction.

same USB connector as before, it is possible that the computer has detected the M-100FX
incorrectly. Re-install the driver.
