If you want to hook up several ones of those via a USB

that this hub has a separate "Transaction translator" per port so that
a USB1.1 transaction from one Midi interface does not keep other
transactions from happening: the 12Mbps limitation should only be per
Midi interface, not per aggregating hub which can talk at 480Mbps to
the computer.
MIDI's speed of 0.03 Mbps is less than one percent of the USB 1.1 limit;
the lack of a transaction translator does not matter at all (unless
other, high-speed USB devices are connected to the hub).
