The LavaPort-Quad hardware appears in Device Manager in two places:
under the Multi-function Adapters tree and as part of the Ports tree.

Please note that the Resources (I/O Address & IRQ) used by the
LavaPort-Quad can only be modified through the LavaPort Parent
device - listed under Multi-function Adapters.

If you wish to change the Com number of either one of the ports on the
LavaPort-Quad (e.g. Assign Port 1 to be Com 3 instead of the default
Com 6), please use the Lava Com Port Redirector Utility. This program
will allow you to change the numbering of your ports

.

Interrupt Resources may be modified for the LavaPort Parent device (see
Device Manager - Multi-function Adapters), but not for individual ports
because all four ports on the LavaPort-Quad share one IRQ. Please note
that interrupt changes require a reboot to take effect.

Modifying I/O Address and IRQ Resources is NOT recommended.
