Hello, Here is the patch to support Winchiphead CH382 PCIe-UART device. I found the board at eBay with cheap price tag.
CH382 has three configurations and different PCI device ID. - 2 serial (2S) - 2 serial and 1 parallel (2S1P) - 1 parallel (1P) I have 2S board the patch does not support parallel port, 2S1P board will work as 2S. After patching, CH382 is recognized as 16750 like this. puc0 at pci3 dev 0 function 0 "Nanjing QinHeng Electronics CH382" rev 0x10: port s: 2 com com4 at puc0 port 0 apic 5 int 17: ti16750, 64 byte fifo com5 at puc0 port 1 apic 5 int 17: ti16750, 64 byte fifo I referred the following pages: http://www.spinics.net/lists/linux-serial/msg11744.html http://kent-vandervelden.blogspot.jp/2014/08/linux-parallel-port-cards.html Can I commit?
