USB connections in the cockpit are used for charging devices in electronic flight bag (tablets etc). I'm not sure if the USB controller is connected to anything else than power supply, but it might still be programmable allowing it to distribute malware.

These are usually available only to maintenance and use digital signatures to verify the data.
