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.
