Troubleshooting

Q1: Windows is unable to recognize my hardware. What should I do?

A1: First, make sure your computer meets the minimum requirements as specified in Section 1 of this Quick Installation Guide. Second, try plugging the TU-S9 into a different USB port on your computer.

Q2: Can I use the TU-S9 with my serial keyboard, mouse, or joystick? A2: The TU-S9 does not support interrupt transfer mode devices. If your

serial keyboard, mouse, or joystick is an HID Device, it is not supported.

Q3: Can I connect or disconnect the USB cables while the computer is on?

A3: Yes, you can connect or disconnect the USB cable while the computer is on, because the USB interface is Plug-and-Play and hot-pluggable.
