The RocketPort USB Modem Hub uses an internally
generated 48 MHz controller specifically designed for
a USB port to operate four modem ports. This device
and its software enable the USB interface to be
transparent to the peripheral and requires no
firmware changes. This makes it possible for
modems to easily interface with a USB port.
