Hey Guys,
Just curious if this is normal behaviour....(For those of you who couldnt be bothered watching the video. Basically the USB3 bus interferes with GPS.

Things I have tried....

1. Change RPi5 PSU a millions times. All USB devices work fine in isolation and RaspOS never gives me a power error.
2. Change gps module. Tried 3. Same results.
3. Tried using different USB3 devices. No change.
4. USB2 devices on USB3 bus work fine, no issues.
5. Added the standard USB power params to config.txt 6. Tried 2 x RPi5 (8gb)
7. Tried a USB-Serial (ttyUSB0) same results to local GPS.

Any suggestions what to try next???
