Playstation 2 [SCPH-77003] & USB memory sticks, any pointers...?

I would like a comprehensive understanding of what the console is capable of doing with the USB..., ...& what else is required for additional capabilities?

The sites I have visited detail making boot disks, but require a means of bypassing the system halting on unrecognised disks.

I see an explanation of running games from hdd via USB [backup copies] yet so far haven't ascertained if the USB will take a memory stick or other storage device and enable transfer to/from the memory cards, like maybe Codebreaker does this...[?]

So far I'm looking into,

CDGenPS2,

FreeMCBoot [&Tools],

HD Project v1.07 to make MC on usb stick

Open PS2 Loader

Swap Magic

USB Extreme, PS2 games from HDD+USB

- but it's a like a jigsaw of something blurred with bits missing, pieces from another puzzle and no lid with the picture on....

If the question is simply:

- With a USB memory stick/external HDD in a PS2 console, is there a way to transfer to & from the slot 1 & 2 'Magic Gate' memory cards?

...namely, a step by step description of a way to ~ ?

Or....

If the console is connected via it's ethernet connection to a router - does it have a device webpage and read/write access to MC data - again with any required steps...?
