You'll have to include more information. What exactly is the error message you get? Also, what is the name of the hardware device (more specific than WUSB)?
So i try to install this driver for my WUSB11 v2.8. I know there are a lot of things about this in google but its not explained to good. Im trying to install that at76a503c driver. Whats happening is im unzipping it, then using make and make install and getting this error. This is on Fedora 4. I get something like Error 1 to 4 and everything goes wrong. Maybe someone know the error, i have to go get it. But if u can answer it without knowing the exact error please help.
