Could anybody please point to a powered hub that is known-working with RPI4 bullseye?
Thanks,

That you very much for clarifying. Oh, well I guess that hub will have to be put to other use....
It is a design flaw of your hub. It is actively driving the data lines even when the host is off. This is causing some leakage through the ESD protection onto the internal Pi power rails. The Pi PMIC will refuse to power up from off in this situation as it enforces strict sequencing of the power rails.
Fix is to get a different hub. You can try adding another hub between the Pi and this hub as well. It doesn't need to be powered.
