Problem ansluta ESP8266, dmesg

[Oltronix]

Försöker ansluta en Wemos ESP8266 till en Linuxburk, Ubuntu 22.04.5 LTS
Linux HP 5.15.0-160-generic #170-Ubuntu SMP Wed Oct 1 10:06:56 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

Då händer följande och jag får förståss ingen kontakt med ESPn

När gör samma sak med en Raspberry Pi så ser det ut så här, och jag får kontakt med ESPn

Vad kan det var för problem? Jag har testat flera ESP8266-kort.

Om du inte är synskadad så avinstallera BRLTTY
