The idea was suggested by the fact that your devices worked okay when plugged into the docking station, which has its own hub. The only thing I can think of is that your monitor's hub must be different in some way from the hub that is built into the motherboard (the one that shows up as Bus 02 Port 1 Dev 2 in your lsusb -t listings). But I've never heard of anyone having problems with those on-board hubs before, and I don't know why it would behave differently under Linux vs. Windows.
