Abstract: Disclosed is a capsule that can be attached to a vaporizer and that stores consumable material for consumption by a user. The capsule can include a reservoir that is heated via a heating device and is attached to the vaporizer by a serial bus connection such as a universal serial bus (“USB”) connection. The USB connection can facilitate electric and mechanical coupling with the vaporizer, and further can provide a means to transfer usage data from the reservoir to the vaporizer.
