When installing the USB teletap, windows will install the
required drivers. Windows doesn't always detect the device
correctly after installing the drivers. This will cause the
USBClient not to detect the recorder.
Solution 1:
Close the USBClient
Pull the USB Teletap out and insert it again.
Use the same USB port if possible.
Now start the USB CLient and it should be working.
Solution 2:
Close the USBClient.
Open the Hardware Device manager of windows.
Find the USB Audio device that is not working correctly and just
use the Update Drivers button.
