Abstract: Techniques are disclosed for enabling an integrated sensor hub of a main computer to access a detachable peripheral device. In an embodiment, a system includes a main unit having a peripheral interface, an embedded controller, and a device controller. The peripheral interface is configured to be detachably coupled to a peripheral. The peripheral includes a control unit and an input/output device. The embedded controller is configured to communicate with the control unit of the peripheral via the peripheral interface while the peripheral is attached to the peripheral interface. The embedded controller includes at least one data register, and in some embodiments, a set of data registers, configured to store data relating to the peripheral and to the corresponding input/output device. The device controller is configured to read data from the data register(s) of the embedded controller, write data to the data register(s) of the embedded controller, or both.
