Samsung I7500 :: Make Adb List Galaxy?

i know you all gona say that i should have used forum search which actually i did and i still cant find the answer of how to root (most resent or best methods). today i decided to go the way most of you went and root my galaxy so i could enjoy some of the features or customise the devise for it to be either faster or better somehow (particularly im interested in fixing HW acceleration of openGL). but my main problem is still that ADB doesnt show my device in the devices list after adb_devices command... i think ive tried everything: reinstalling drivers and NPS, SDK 1.5 r1 putting in debbuging, restarting phone even using USBdeview soft to uninstall all android and samsung drivers and try to make it work but still nothing... all day wasted, many forums read, downloaded KAM187s drivers and still nothing im on H8 firmware how to make adb recognise my phone and list it) plus i want some info on how to push this openGL fix on my phone after i root it (if ever) by the way tried on Windows 7 and XP sorry for making a new thread but i think im not the only one whose phone is not listed by adb as i read it on other forums.
