I am seeing Zero4U USB ports dropping out on my Raspberry Pi 2 Zero. They are working, then drop out and come back in a few seconds. This keeps the GPS on USB from working and also the CM108 audio chip to stop and restart. I am using this for APRS, and I am wondering whether the Raspberry Pi's power supply does not provide enough current. if not how do I power the board, and can it power the Raspberry Pi 2 zero?
Does your Raspberry Pi 2 Zero have WiFi ability?
It seems the USB stack gets reset due to interference. Have you installed the ferrite ring and metallised PET membrane included in the package?
@admin Yes I am running wifi to control the raspberry pi 2 zero w. This is running digirig software. I have the ferrite installed as shown in the manual. I do not have the membrane installed and I will look for it. I can see what the ferrite does but not the membrane. I do think the USB stack is being interrupted and I thought it was power but maybe not.
