Right, im having issues at the first part:
How to Install Drivers (ex ADB)
First things first, you will need to install the Samsung drivers for your device if you are using Windows 7 (or probably Windows Vista (God Forbid)) all you need to do is plug in phone to the USB port, mount the Drive by dragging the top bar down and selecting mount.
Then go to Settings >> Applications >> Development and select USB Debugging and them mount the drive again.
If you have problems install Samsungs latest PC Suite from http://www.samsungmobile.co.uk/support/softwaremanuals/software.do
Select the device it will be called Samsung Galaxy, Samsung –i7500 or maybe even Samsung GT-i7500, the naming convention used is inconsistent so it depends on what time of day it is or something like that.
If problems still remain or you run 64x look http://androidforums.com/samsung-i7500/8801-using-i7500-x64-computer-drivers.html
If all you want to do is update firmware via Odin you can stop there for the ROMS there is another driver you need but see below for that.
When i mount in debuging mode, XP picks up the phone and launched the New HArdware Wizard, but cant do it automatically, and i dont have any driver files to point it to. Simultaneously, NPS launches with a GT-i7500 icon which when i click on, pops up a "device not supprted" notification. What am i doing wrong??
