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,
