Hi Everybody,
I have a problem with my UZB-Stick on a Raspberry 3B+. I have the original power supply and already tried another power supply and a powered USB-Hub. There is no other hardware connected to the pi. But I have the Problem that my UZB-Stick is not recognized when I power down / up my Raspberry. The LED of the stick goes on…then off for short time(power-drop?) and then goes on and just keeps blinking (~1Hz) whereas if everything works fine, there is no blinking.
The workaround is to power up the Raspberry without the stick…then plug in the stick (blinks 3 times with 1Hz and then LED goes off) and make a restart of HomeaAssistant server. After that it shows up in my hardware
/dev/serial/by-id/usb-0658_0200-if00
/dev/ttyACM0
When it is not recognized, both lines are missing under serial.
Do you have an idea, what I could do about this? I am a Linux noob - are there log-files I could provide to analyse the problem?
Is it a problem of the UZB-Stick?
Or is it a problem of my Pi with power-supply during Bootup?
Thank you!
