Hi,
"technically" the Hub can be powered externally, but it isnt a must, it can happily drive a mouse and Keyboard when connected to the PC without PSU. The Pico itself is powered though 5V 2A, so there is in theory plenty of it.
The thing is: If if wouldn't communicate with the Pico at all, PM should already reject the Hub at the moment he is plugged in with the same fault, without any Keyboard or Mouse attached to it, but that isnt the case. I suppose i have to dive in deeper, since the "invalid address" can be caused by anything including hardware faults of the RP2040.
Mick, may i ask you which Hub you use?
Best regards
Stef
