Raspberry pi 4 with Openplotter 3 64 bit (with all updates to date) and with ssd boot USB 3 disk.
I connected these devices with tplink powered usb hub (UH720, 7 Ports USB 3.0):
- RTL-SDR Blog V3
- USB GPS
- 3 x Cable Victron Ve.direct
if I connect only the SDR and GPS devices everything works fine. If I connect even one of the victron cables, the serial app stops detecting the devices and sdr stops being recognized.
Note that the problem does not always come out systematically but most of the time.
The problem also comes out if I connect 1 victron cable directly from the rpi, so it's not a hub power problem.
If I change boot disk with openplotter 2, the devices are recognized correctly.
I also tried to change the usb hub (before I had the TpLink UH700) but the problem is the same.
I also talked about it here: https://forum.openmarine.net/showthread....675&page=7
Interesting that despite the gps being reported as missing by Data Browser it works correctly. While the SDR device sometimes stops working.
In debug mode
