That datasheet clearly states that it uses a PL2303 which is a
different chip.

Sure, the id looks like they could be for a CH341, but please clear up
this apparent confusion (i.e. explain it).

And include the output of 'lsusb -v' for reference.

Please get into the custom of running scripts/checkpatch.pl on your
patches before submission, which would have let you know about some
spelling errors and unbroken lines.

And add a patch revision to your subject prefix (e.g. PATCH v2) when
resending and include a short changelog here so we know what changes
since previous versions.
