I am having a lot of problems with a powered usb hub from waveshare. This one (https://www.waveshare.com/usb3.2-gen1-hub-2in-4out.htm)
After a lot of plugging in and unplugging, sometimes all my accessories are connected (smart shunt, mppt and multiplus). Then 3 lights are on to show thr 3 connected usb devices. But after a reboot or unplugging the cable and re plugging, it almost never works.
The hub is a few months old now and works okay till a reboot and then i have no idea how to make it work again till it suddenly starts working.
The hub is powered with 12v (13.5v measured from lifepo4 batteries from the motorhome)
