edit2: FIXED Bit more searching and i found i had to add the vendor/product id to the kext. Works fine now! yay! 
So, cant get my belkin USB wifi to work. Chipset is RTL8187B.
Tried the following drivers, 87_Mac10.4_v1309, 87B_Mac10.4_v1117, RRTL8187B_MacOS10.4_1088. Non of which work

Specs:
Aspire 3610 Laptop
Intel Celeron M - SSE2 Only
Intel GMA900 - working fine
Sound - dunno wat it is, working fine though
USB Ports - all working
No SATA - All IDE as its a fairly old laptop
There dosnt seem to be a problem installing the drivers. All of the driver packages i've tried install with no errors, problem is none of them seem to want to fire-up either the USB stick or the 'Realtek WLAN' app, so there isnt a new device in Network preferences or anything. Even after multiple install/reinstalls of the driver, the app still hangs and i have to force quit. The usb device still shows up in System Profiler though, so i guess its 'there'.
Tried iATKOS r3 and Uphuck 10.4.9i and no luck with either. Downloading Jas 10.4 at the mo to see if that will help.
Any ideas?
Cheers,
Woj
