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, - -- Xin LI <delphij@delphij.net> https://www.delphij.net/ FreeBSD - The Power to Serve!
