Troubleshooting - Philips SpeechMike LFH3200 User Manual

5. Troubleshooting

Problem
The operating system stops
responding after restart
The SpeechMike is com-
pletely without function
The SpeechMike is connec-
ted to the computer but
sound will play on the com-
puter's speaker only
Cause
Using the Philips SpeechMike together
with certain USB hubs may cause the op-
erating system to stop responding when
the computer is started.
Some computer providers limit the output
power of USB ports to 100mA. These ports
may not provide enough power for the
SpeechMike to function properly.
SpeechMike is not selected as the default
playback device.
Solution
Unplug the SpeechMike before starting
the PC and reconnect it afterwards. We
recommend replacing the USB hub or
connecting your SpeechMike directly
to the USB port of the computer.
Connect the SpeechMike via a self-
powered hub.
In the Windows sound settings, select
SpeechMike as the default playback
device.
