What names?

Google says that this device has several possible input routings.
Did you configure it for the correct input?

This is normal for many of these kind of devices; mixer controls often
are implemented in hardware only.

However, if these settings must be done from the computer, they are
implemented with unknown vendor-specific commands.  In that case, you
would have to try to run the Windows control panel from within a virtual
machine (while unloading the USB audio driver).
