unfortunately windows 98 se does not have that usb mass storage device driver built in like xp/2000/me does,windows me has that feature but xp's,implementation is quite better, win 98 se you need drivers no matter what,if say you had the lexar media jumpdrive elite,it supports windows 98 se up to xp but for windows 98 se you need drivers,the rest you don't because the mass storage driver is built into win me and onwards where on 98 se it is not,if you install the windows 98 se sp 2.0 rc1 it adds it but you may still need drivers.hope this helps.
