Internet has many clips on non-linux system that shows working "SP Flash
Tool" with specific CDC driver.
Unfortunately is not clear config

Prolific has developed a new USB to UART chip: PL2303HXN

The Vendor request used by the PL2303HXN (TYPE_HXN) is different from
the existing PL2303 series (TYPE_HX & TYPE_01).
Therefore, different Vendor requests are used to issue rel

We are not as likely to be vulnerable as storage, as it is unlikelier
that UAS is run over a controller without native support for SG,
but the issue exists.
