+@item net:@var{nic_num}
+Network adapter that supports CDC ethernet and RNDIS protocols.  This must be
+used together with the @code{-net nic,model=usb,...} option (see description),
+where @var{nic_num} specifies the index of the @code{-net nic,...} option
+describing the interface (zero-based).
+For instance, user-mode networking can be used by specifying
+@example
+qemu -net user,vlan=1 -net nic,model=usb,vlan=1 -usbdevice net:0 [...OPTIONS...]
+@end example
+Currently this cannot be used in machines that support PCI NICs.
