Guten Abend Forum,
aktuell habe ich ein sehr komisches Problem. Ich habe einen CC2531EMK Coordinator an meinem Raspberry Pi 4B angeschlossen.
Das hat auch soweit super funktioniert. Seit neustem geht die grüne LED am Stick nach dem Boot-Vorgang einfach aus.
Ich kann daher den Stick nicht mehr nutzen und bin gerade auf der Fehlersuche, aber ich finde ihn nicht.
root@raspberrypi4B:/home/pi# dmesg | grep ttyACM0
[ 2.462500] usb 1-1.1: Manufacturer: Texas Instruments
[ 7.153926] cdc_acm 1-1.1:1.0: ttyACM0: USB ACM device
Die USB-Infos fehlen:

Beim aussteigen sehe ich folgendes im kernel-Log:

Kennt jemand den Fehler?
Ist der Stick kaputt?
Ich habe den Stick bereits geflasht gekauft. Habe keine möglichkeit hier, den Stick frisch zu flashen.
Den Cache von OpenHAB habe ich bereits auch geleert.
Good evening forum,
currently I have a very strange problem. I have connected a CC2531EMK Coordinator to my Raspberry Pi 4B.
This has also worked great so far. Recently, the green LED on the stick simply goes off after the boot process.
I can therefore no longer use the stick and am currently troubleshooting, but I can not find it.

The USB info is missing:

On exit I see the following in the kernel log:

Does anyone know the error?
Is the stick broken?
I bought the stick already flashed. Have no way here to flash the stick fresh.
I have already cleared the OpenHAB cache as well.
