I found a datasheet:

	http://wch-ic.com/download/down.asp?id=116 (English)

	and

	http://winchiphead.com/download/CH352/CH352DS1.PDF (Chinese)

And I think John's patch is right, I've added a new PCI ID for it
though, found from the datasheet.  Did you have uart(4) in your kernel
(remove my old patch)?

Cheers,
