Hi @howil , thanks for the detailed report.
Do you think these problems occurred on your Mini since you received it, or did they begin later? Do you think you updated the firmware at any point?
Could you try the USB port tuning preview build I posted? Librem Mini v1/v2: Feedback request for USB tuning preview build Please read the description, as I’ve applied different tunings to different ports in order to get feedback on multiple tunings in one build.
