Here's my typical workflow for installing Ubuntu/Mint:1) Boot from a USB stick with Live installation2) Install, reboot3) Use my USB network adapter which is supported by Mint to get internet4) Go to Additional Drivers and install the driver for my PCIe network card5) No longer use the USB network adapter as my PCIe card is far betterWhen I try to install Debian, it does not have drivers for either of my network devices. How would I go about installing the driver for either of my network cards on Debian? It's tricky because I cannot use the internet to get any of code or drivers. 
How can I install my network driver on Debian from a USB media?
