Frequently asked questions

The operating system stops responding
after restart
Using the Philips SpeechMike together
with certain USB hubs may cause the
operating system to stop responding
when the computer is started.
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.
The SpeechMike is completely without
function
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.
Connect the SpeechMike via a self-powered hub.
