The update to the release 11.3 HAOS does not solve the issue. Workaround: Downgrade to 11.1

In my case I didn’t have the line, I added it but still no luck.

dwc_otg.lpm_enable=0
console=tty1

afaik this needs to be on the same line , like this:

dwc_otg.lpm_enable=0 console=tty1

Downgrading to 11.1 was the solution I went with as well.

@KNXBroker @mnorrsken That looks like completely different issues - this one is related to serial console pins on the RPi pin header. If you’re having problems with USB devices, please create a new issue with more details.
