If you’re referring to Windows drivers, they are usually in a folder containing an inf file. ndiswrapper requires Windows XP drivers to work. Some manufacturers might hide them inside their installation packages. (You might be able to use the cabextract command or open the EXE as an archive to extract them out) 
Linux drivers are unlikely to be on an installation disc, I’d be surprised if they are, which is why we’ll need to research your model to find the right ones.
Also, your lsusb output is insufficient, is it a USB adapter? If it’s a PCI card or built-in, try lspci instead.
