Need help installing WUSB54G!! (Linksys wireless USB internet card)

[Sconts]

I have an AMD64 x2 4800+ processor
and Kubuntu Feisty.

I have installed ndiswrapper, and properly installed the wusb54g.inf driver file.
When I enter

ndiswrapper -l

I get

wusb209x.sys : invalid driver!
wusb20xp.sys : invalid driver!
WARNING: Failed to open config file /etc/modprobe.d/blacklist.save: Permission denied
WARNING: Failed to open config file /etc/modprobe.d/blacklist.save.2: Permission denied
WARNING: Failed to open config file /etc/modprobe.d/blacklist.save.3: Permission denied
WARNING: Failed to open config file /etc/modprobe.d/blacklist.save.1: Permission denied
wusb54g : driver installed
    device (5041:2235) present (alternate driver: prism54usb)

From what I have read on these forums and various other forums, it seems that all I need is for the .inf file to work...and according to this, it does. However my device is still not recognized. Any ideas?
Thanks

Also:
When i do "lsusb", it confirms that 5041:2235 is the linksys device. Here's the exact result:

Bus 001 Device 002: ID 5041:2235 Linksys (?)

(yes, it had the '(?)' in the actual code)

The whole "permission denied" thing should scream at you: "SHOULD HAVE USED SUDO!"

sudo ndiswrapper -l
