dbcm/usbexec

Description

This was my 1st attempt to lock my mac when the YubiKey was removed.

Since LaunchEvents don't have the detach event, i converted this SW to a more generic util.

It executes any command after a vendor and product USB IDs is connected.

As a base example, it listens for a YubiKey 1st gen to be connected.

Install

Connect the target device and run this command:

$ system_profiler SPUSBDataType

look for "Product ID" and "Vendor ID", edit org.profundos.usbexec.plist and update those values (idProduct and idVendor)

Install everything in you mac. Run this:

$ ./install

Check if everything is OK. Run:

$ tail -F $HOME/.usbexec/usbexec.log

Connect and disconnect your USB Device. Look for:

Received event: com.apple.device-attach: 4294987900
Events Purger called!
Executing commands... -from_daemon

Add your commands here:

$ vi $HOME/.usbexec/commands

How it works

The main plist file will launch the utility 'usbexec' which consumes the USB attach event (necessary, otherwise launchd will re-launch usbexec every 10 seconds), and then calls your commands.

Notes

The detach event is not reliable, see yklock
