Troubleshooting
Does your computer or USB hub have sufficient power supply capacity?
The UM-1G cannot be connected if insufficient power is supplied to it. Check whether one of
the following cases apply.
• If you are using the UM-1G with a notebook computer that is running on its battery,
operation may be unreliable with some models of computer. 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 UM-1G 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).
Could numerous applications be running?
It may be that there is not enough memory for another application to start up. Close other
applications before starting up another application. If an error still appears, try restarting
Windows.
Could other software or resident software (such as antivirus programs) be running?
If other software is running, the application may not start up correctly. Try closing the other
software before you use the application.
