Mini PC T9Plus with D4-300 TerraMaster DAS
Installing Debian GNU/Linux
It seems that Linux kernel 6.1.0 (as shipped with Debian 12 Bookworm) still does not support the WiFi adapter RTL8852BE.
The RGB rainbow LEDs
The T9Plus Mini PC has a strip of RGB LEDs all around the case; the default behaviour is to play a circular rainbow effect, rather nice the first time that you see it, but utterly annoing after a couple of hours!
You can program the LEDs with several visual effects, brigthness and speed by sending some specific commands to the USB serial adapter exposed to the operating system. The manufacturer provides a Windows program to configure the LEDs, but several users on the internet reported that the program (named LedControl.exe) is detected as a malware by several antivirus software. I never run MS-Windows on this PC because I booted and installed Debian GNU/Linux since the very first boot, so I cannot give any insight on it.
Fortunately enough, someone made the reverse engineering of the serial protocol required by the LEDs controller and published a working code. Then I wrote a Python program to make the programming.
