How to decrease port speed for lirc?

Question

linux

There is a USB-UIRT based on PL2303, bought for a spear in China. With the help of it, such an IR receiver was made:


When you press the buttons on the remote control, the LED blinks, but nothing more.
If I start minicomand set the speed to 2400 baud, then I start to receive characters.
If I change the port speed and run cat:

$ sudo stty -F /dev/ttyUSB0 2400
$ sudo cat /dev/ttyUSB0

I also receive data.
But mode2they lircdrefuse to work. As far as I understand mode2 changes the port speed:

$ sudo stty -F /dev/ttyUSB0 -a
speed 2400 baud; rows 0; columns 0; line = 0;
$ sudo mode2 --driver=uirt2_raw --device=/dev/ttyUSB0
Using driver uirt2_raw on device /dev/ttyUSB0
Trying device: /dev/ttyUSB0
     <жму кнопочку пульта>
Using device: /dev/ttyUSB0
Running as regular user master
readdata() failed
$ sudo stty -F /dev/ttyUSB0 -a
speed 115200 baud; rows 0; columns 0; line = 0;

How to set the speed of the port ttyUSB0? Or can the problem be solved in another way?

Answer 1

You can try using udev. On connecting the device, hang up the execution of the script with the settings you need.
