Need Help With ndiswrapper and knoppix

[jallirs]

Alright guys, i downloaded the most recent iso for knoppix(4.0.2) and burned it to a cd,
i run a windows box and am trying to switch over to linux, but want to make sure i can get my hardware to work in linux first
i booted up and got into KDE no problem,
i tried to open up the browser included in the os, but it was obvious that i wasnt connected to the internet, (ie no lights on my Linksys WUSB54G (uses prism54 chipset, but is usb) were blinking)
so i tried to configure it with ndiswrapper
i copied and pasted the inf file(WUSB54G.inf) and all the other files in the driver directory that i downloaded from the linksys website to the desktop manually, then started bash and switched over to root using the su command.
i navagated to the desktop, and issued the following commands:

ndiswrapper -i WUSB54G.inf
then i did:

modprobe ndiswrapper
but it came back with this:

FATAL: Error inserting ndiswrapper(/lib/modules/2.6.12/misc/ndiswrapper.ko) Operation not permitted
What am i doing wrong?

Thank you

put sudo in front of those commands:
sudo modprobe ndiswrapper

tried it with sudo and still got the same error,
mabye its because the place its trying to write to is a read only medium(ie a cd)?
do you think if i put it on my ram it would work?
