This command line tool will iterate through all connected Philip devices and try to switch the sampling rate to 44kHz.
After switching, the device will re-connect itself.
Be aware that switching can only be successful if the device is not currently recording or playing back audio.

How to use:
1. Connect SpeechMike(s)
2. Run tool
3. Wait for SpeechMike(s) to reconnect
4. For verifying whether switching was successful, a tool like USBDeview can be used. The SpeechMike should have ProductId 0xc1d now instead of 0xc1c.
