Subject: WCH CH352 PCI-to-RS232 card bad default type
Date: Thu, 21 Mar 2013 13:14:23 +0600 [thread overview]
Message-ID: <514AB34F.9060707@yandex.ru> (raw)
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
