Check dmesg when you plug it in - is it detected?

Try checking out lsusb - can you figure out what driver is needed?

Make sure you have CONFIG_USB_SERIAL set in your kernel.  You probably
also need the appropriate driver for your adapter.  I have PL2303 set
for mine.  Here is my lsusb output for the serial ports:

Bus 002 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial
Port
Bus 002 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial
Port

If the kernel doesn't have USB_SERIAL support enabled you definitely
won't get a ttyUSB device.  You also need hotplug properly configured,
but that should pretty-much work out of the box with gentoo.  You might
need to tweak it if you have more than one and want to ensure it gets
the same port each time (wouldn't do to have my two mythtv satellite
boxes getting random assignments every time I reboot).
