i have the same issue using mate 64 bit using the installer script for ubuntu 64.
a problem is, that the /dev/ttyUSB0 is not created, but why?
is saw a /dev/ttyAMA0 device...

I used to have the fan control working with an earlier version of raspios 64 bit but now the service will not start. I was trying to get pop-os fan control working which is not listed as a supported distro so I went back to raspios 64 and no go there either. Is fan control working anywhere with current distros?

[noanight]

@ddetton you may have a look at this issue 142...i got it running with Ubuntu mate 64 bit.

what version of your raspberry pi 4B？ V1.4 or V1.5 ? it seems like your raspberry pi 4B's USB-C port has some problem with it.

[yoyojacky]

fan spinning requires some conditions:

1. Your OS can detect the serial port via USB-C port of Raspberry Pi, there may generate a serial port called "/dev/ttyUSB0"
2. You need to send "PWMXXX“ to this serial port , XXX dedicates 000 to 100, it means the PWM dutycycle's value from 0 to 100, for example, if you send "PWM075" means let the fan spinning at 75% speed.
3. It can be drive in C language or Python language, if you want to use python script, you may need to install pyserial library to drive the serial port.

I have just create a brench on feature/bookworm and it under testing .

I have test it on UBUNTU 24.04 LTS but no luck, it seems like the dwc2 overlay is malfunction. I am trying other way to recognize the serial port on daugherboard of deskpi.
