Ok, what i will write here is the information based by other people`s expirience on various newsgroups and my own expirience.
This is all i can tell you about problems with USB drives, so...
-My USB stick is a USB stick/Mp3 player (TakemMS,USB 2.0,256 Mb)
and it did not work.
-I`ve tried 3 USB/mp3 flash drives and none of them worked so...
try out with the plain usb stick`s.
-Try using different USB stick, try a few (borrow from a friend or something)
-The thing is, as far as i know based on my expirience, all drives
dont`work and that`s it.It can be due your ps2 or your stick.
(Maybe that depends on your version of PS2, mine is SCPH-70004)
-PS2 USB ports are 1.1 but it worked with my USB 2.0 drive
-AR MAX also wont`t recognize all USB drives, i don`t know the list of
ones that work or don`t work and i think that no one knows that
SOME TIPS:
-try using different USB slot on your PS2
-try formating your USB stick (FAT 16)
-make sure your option file is in max drive format (.max)
or AR MAX won`t see it (and all other save games)
-try using plain USB stick in different versions (maybe your ps2 cannot
recognize 2.0 USB drives, try 1.1 USB drive or maybe AR MAX cannot recognize your USB stick at all,try a different one)
-based on other people`s expirience i read that brand name drives like
Kingmax or Corsair work without problem
-My friend`s drive that i borrowed ( now it`s mine
) is TakeMS,256MB,USB 2.0 (plain one,not mp3) work`s perfectly
-When you buy AR MAX you get a 16 MB USB 1.1 drive with him, so
try older 1.1 USB drives...
So my conclusion is:
Try all kind of USB flash drives and you`l find one that works,
as i mentioned in the original post, it does not work with every one but with most of them it works!
I did not try this on non chipped/modded ps2 so i dont know if it works,
my ps2 is modded,but if you can load burned cd`s on your ps2,
i think it must work!
