Synchronizing device association data among computing devices

Device association data for peripheral devices, which is data used to connect to the peripheral devices, is maintained and synchronized across multiple computing devices associated with a user account on a service. When a new peripheral device is associated with a computing device, device association data for the new peripheral device is added to the computing device. The device association data for the new peripheral device is also sent to the service, which provides the device association to the other computing devices from which the user logs into his or her account, and those other computing devices in turn automatically associate themselves with the peripheral device. Device use data describing how a user desires to use the peripheral device on one computing device, as well as changes to the device association data on one computing device, can similarly be synchronized across the multiple computing devices.
