During these experiments I found something very weird :) The RPi has two dongles: WiFi and BT Things *do* work, if the LAN cable is plugged in - even if the interface is down in the system. The moment I pull the cable, I soon get the familiar buffer overflow and a flood of errors. How is that possible? :) That’s without a powered hub so far. > I always had strange/random problems on RPi with USB HW plugged > directly on the USB port (except for pen drives, which work fine), > even for devices which supposedly draw very little current. > > Given that you are disabling duplicate filtering, every single > Advertising packet is arriving at the host, so it is certainly using > more power. Just not sure if that is the cause. So where is the filtering done? In the kernel driver?
