Problem

Cisco ASA firewalls have had USB sockets on them for a while, but a dig into the documentation only yielded, ‘for use in future releases’. Well they are working now!

Note: Firewall shown is a 5516-X (running version 9.8(1))

Solution

Your drive needs to be formatted as FAT (not NTFS), I’m going to update/install some AnyConnect client software, but there’s nothing to stop you uploading a new IOS or ASDM images.

Your drive will get mounted as ‘Drive1’ (unless you have a secondary flash drive onboard already).

Note: I have seen drives not get recognised like so;

[box]

Petes-ASA# Extra storage device is not supported.

Petes-ASA# show disk1

--#--  --length--  -----date/time------  path

No files in directory 

[/box]

If that happens to you, you will need to reload the ASA (assuming the drive is formatted correctly) before it will be recognised.

You can then copy the files to the main flash (disk0:).

[box]

PeteASA(config)# copy disk1:/anyconnect-linux64-4.5.01044-webdeploy-k9.pkg disk0:

Source filename [anyconnect-linux64-4.5.01044-webdeploy-k9.pkg]? {Enter}

To prove the file is in the main ‘flash’.
