Vista - Hardware problems...

i don't know if anyone has posted this problems with this devices or not...if
they did i'm sorry. I've had problems with 3 things on Vista, first of all
was my creative audio PCI that was not able to install, then my Lexmark
series X1100 (my model is X1190) that installed but was unable to work and
then the most important of all and main reason why i went back to my old
windows XP, my Philips SNU5600 (usb wireless adapter) and so i wasn't able to
go online on vista making it useless on my pc.is there anyway around
this?because first time i installed it on my second hard-drive, i managed to
go online just ok but then when i decided to make vista my main operating
system (formated my hard drives and installed vista on main) it didn't work
anymore.
