    I just meant to indicate that I probably can't help you,  as
    I just idly  wondered whether my  laptop had a  /dev/ttyUSB0
    too, as a standard thing, and it did not.

    So I wondered if your device might actually be available  on
    your system under a  different name than /dev/ttyUSB0,  e.g.
    /dev/ttyS0 (which  has mystery  colored underscore  tail  as
    your listing appears on my display: [ /dev/ttyS0    ].

    I don't know where the standard for naming is defined, or if
    it comes from  module whose author  can define custom  names
    for software for  a particular  device, or  anything else  I
    might speculate about, but this  email has used up the  last
    of the time I have for this. :)

    Sorry not to be more helpful.
