[Voyage-linux] Error connecting multiple PL2303 Serial Converter

[Pippo Pippo 77]

Hi Michael,
and thanks for your help.
I have a couple of question regarding cp210x adapter, and I would
appreciate if you can help me.

1) Do voyage 0.5 with 2.6 Branck kernel have driver for this?
2) Do voyage 0.8 with 3.0 kernse have driver too?
3) Do you know if exist multiple adapter based on this chipset? For example
1 USB but 2/4 serial Port?


Many Thanks
