Hi Everyone, I'm trying to track down the cause of some garbage in a response when using an ELM327 (https://www.elmelectronics.com/ic/elm327/) with a CH341 serial controller. I see there's been a fair amount of activity with the CH341 (https://github.com/torvalds/linux/commits/master/drivers/usb/serial/ch341.c), but I can't tell if its been backported to the 5.4 kernel. Specifically, the 5.4.0-77 kernel supplied with Ubuntu 18.04 and Mint 20.1. Does anyone know if the fixes and improvements for the CH341 have made their way into the 5.4 kernel? Thanks in advance. Jeff
