There is a patch https://github.com/karlp/ch341-linux/blob/master/0001-usb-serial-ch341-Add-parity-support.patch which enables parity selection for the ch341 USB-RS485 adapter. From: Karl Palsson <karlp@tweak.net.au> Date: Tue, 18 Mar 2014 23:33:27 +0000 This adapter is available for cheap on eBay. The patch made me able to use this adapter for polling my modbus power-meter with raspberry pi. Would it be possible to get this into the official distribution? Leif

Kernel 4.10 has commit ba781bdf866 ("USB: serial: ch341: add support
for parity, frame length, stop bits") that adds parity support for
this driver.
Have you tried using 4.10.x?
