PS2 modifiers  

i have a ps2 with the versions: console SCPH-50001, browser 1.40, cd player 2.00, Playstation Driver 1.11, and DVD player 3.00U.

i know some of you here modified their ps2 already, and the thought here is, my lens cannot read anymore, and i want to modify it in order to play games using HDD. and by NOT using Mod chips, cds, and DVDs, but the thing is i have researched, read and tried all of the possible exploits just to hack my ps2 without using a cd or dvd, but non of them work. buying new lens is a lot more expensive.

My question is:

Is it possible to a unhacked ps2 to boot in USB?(because i tried also free MCboot but it won't boot also using my USB, because thats the only way i've got)

Another thing is, Is it possible also to exploit my memory card install software using other PS2(not mine)and then use my Memory Card again to MY ps2 so that it can boot softwares like HD loader?

and by networking, i don't have networking cables and i don't know how to connect it into my computer so that i can modify or exploit my PS2, so can you tell me what to use?

Thanks a lot for your response, I'd really appreciate it if there's any.
happy my loting ang gaming.
