Today I had the roughest Ubuntu installation ever. The problem was the lack of documentation to get ndiswrapper and SMC adapters working. After some reading and trying, I’ve figured out the solution:

Edit /etc/modprob.d/blacklist and add:

blacklist bcm43xx
blacklist islsm
blacklist prism54usb

Edit /etc/modules and add:

ndiswrapper

After this, download the Windows driver, extract it to a folder and do the following:

sudo ndiswrapper -i (driver name).inf
sudo ndiswrapper -m
sudo depmod -a
sudo modprobe ndiswrapper

Reboot and you’re ready to go! It will probably work for any wireless usb adapter that needs ndiswrapper.
