-====== USB Autorun ======
-This feature can be used to automatically launch a shell script or perform a software/config update as soon as an USB storage stick has been plugged in. For authentication, a file called ''autorun.key'' must exist in the root directory of a FAT16/32 formatted stick.
-It can be downloaded from that page and holds the SHA256 hash key of the admin password. The file can hold multiple hashes which will be processed line-by-line during authentication which can be used for setting up more systems with different admin
-passwords. For new devices with an empty password the hash key
-''e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855''
-can be used.
-The hash keys can be generated by running the command ''echo -n "<admin-password>" | sha256sum'' on a Linux system or an Internet hash key generator (search for "sha-256 hash calculator").
-Once authentication has succeeded, the system scans for other files in the root directory which can perform the following actions:
-  - For running a script: ''autorun.sh''
-  - For a configuration update: ''cfg-<SERIALNO>.zip'' (e.g. ''cfg-00112B000815.zip''), or if not available ''cfg.zip''
-  - For a software update: ''sw-update.img''
