Insteon PLM via usb to serial adapter

Hello
Is it possible to use a PLM via a usb to serial adapter. I don't have any serial ports and no available pci slots to add a serial card. The following is the output from lsusb:

Bus 008 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

I couldn't find anything on the wiki on how to setup and test connectivity for the right port.
Thanks
William
