Hi Greg,
Because the "confidential" message is auto add by Prolific's email server.
I will use "charlesyeh522@xxxxxxxxx" to avoid "confidential message".
And I will use Linux kernel 4.4 (pl2303.c & pl2303.h) to make patch file, is it OK?

That's fine, one simple difference does not require an entirely new
driver. Just handle it as a "which chip am I talking to" to determine
what the request value should be.
And this is going to have to be my last response to you, with that email
footer on the message, or my lawyer is going to get mad at me...
thanks,
