Hello.
According to manufacture chip information from
http://wch-ic.com/product/pci/ch352.asp type of emulated chip cannot be
16C550A (it is default value in linux and in patch
https://lkml.org/lkml/2013/3/2/30 ). Correct value is 16550.
Therefore I need to run additional command
setserial /dev/ttySx uart 16550
Default value 16550A is not working, correct value 16550 is working on
my PCI-RS232card.
Please somebody make changes to module
drivers/tty/serial/8250/8250_pci.c (as I think).
Regards,
Vitaliy
