The h300 does have a hardware USB-ATA bridge, but it (at least the international version) also has an OHCI controller

The PP502x does indeed have a controller that can do host side (still hardware, no USB is pure software), but that's not enough for host support. For that you also need things like a PHY that supports host (I think it's there on PP, but I'm not sure), possibly the right pin connections (not sure), and definitely a 5V power supply to the connector. None of the rockbox-supported PP502x players have that.

now that the necessary parts for usb controler are known, why not make a table and step by step insert which player has 5V out and which hostability(no matter how).
Maybe a selfemade controler with 5V at an other port or by battery.
or! with an Diode put 5V at the usbVCC pin! so every player with usb should can have 5V out! ok ok no warranty needs a decision.

Because there is no VCC pin on most or all PP targets.
