    The USB to Serial converter would have a chip inside.
    The Linux kernel supports many of these devices already.
    If your kernel has those modules built then you will not need to do anything more than plug it in.

    After plugging it in ... take a look at the last lines of output from the dmesg command.

    I have a USB to Serial converter that uses the Prolific PL2303 chip.
    This is my dmesg output:
    Code:
    usb 2-1: new full speed USB device using uhci_hcd and address 2
    usb 2-1: configuration #1 chosen from 1 choice
    usbcore: registered new interface driver usbserial
    usbserial: USB Serial support registered for generic
    usbcore: registered new interface driver usbserial_generic
    usbserial: USB Serial Driver core
    usbserial: USB Serial support registered for pl2303
    pl2303 2-1:1.0: pl2303 converter detected
    usb 2-1: pl2303 converter now attached to ttyUSB0
    usbcore: registered new interface driver pl2303
    pl2303: Prolific PL2303 USB to serial adaptor driver



    Men occasionally stumble over the truth,
    but most of them pick themselves up
    and hurry off as if nothing had happened.
