audacity doesn't show WDM

Im using the USB to Guitar device with Audacity, ASIO 4 all and Behringer.
Behringer says to use WDM but it is not listed as a sound option in the drop down menu.
thanks for any help

Assuming that you are on a Windows machine, try the MME option in Audacity, then look for the USB device in the recording input box of the device toolbar.
