Created attachment 237351 [details] dev/puc/pucdata.c for chip WCH382 Th CH382L is a multi-i/o card, usually implemented as 2ser/1par interfaces (or a subset thereof), that fits into PCIe. It is widely avaliable (at least in Europe) under various brand names, e.g. "Delock 90413". It needs a little bit of adjustment to be fully detected by the puc driver, as is in the attachment. The PCI device/vendor numbers used are the default ones. They are apparently EEPROgrammabe, and OEM are advised to change them according to their needs. (But in that case I would expect such OEM to open another ticket here *grin*)
Given that we now use the "patch" keyword, the Summary no longer needs it.
