Hi, hoping someone can help here… As title; I have a Ublox 6M GPS module connected to the GPIO UART RX pin (pin10) and supply power and ground from pins 4 & 5. This works great, and I can see output from the module once the Pi has booted with cpgs -f, and within Astroberry in it's GPS panel This is great, until I plug in the camera on my telescope into the Pi on one of the USB3 ports. When I do this, it kills the connection from the GPS to the Pi. It's only when I plug it into a a USB3 port though. If I plug it into a USB2 port, it plays nice and the GPS continues to spit out data. The full set up is: RPi4b 2Gb Latest image of Astroberry Server imaged to the SD card Ublox 6M GPS module connected as per above Telescope mount (EQ5 Pro) connected over USB (no issues when plugging this on on either USB2 or 3) ZWO ASI 585 MC Camera In the OS I've: Enabled UART via Raspi-Config Disabled the virtual gps - sudo systemctl stop virtualgps / sudo systemctl disable virtualgps Installed GPSD - sudo apt-get install gpsd gpsd-clients edited the GPSD config file to add these options - GPSD_OPTIONS="/dev/serial0 -F /var/run/gpsd.sock" Removed 'console=serial0,115200' from cmdline.txt stopped the serial terminal - sudo systemctl stop serial-getty@serial0.service / sudo systemctl disable serial-getty@serial0.service lsusb output: Code: Select all pi@telescope:/etc/default $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 006: ID 03c3:585b Bus 001 Device 005: ID 067b:23d3 Prolific Technology, Inc.

I’m probably overlooking a setting or restriction on what gets to use what ports etc, but I'm not sure where to look - can anyone help? Thanks, Jason
