A method of implementing USB Host functionality specifically designed to ensure a secure and resilient USB-On-The-Go implementation. A USB Hub Driver is configured so that it is able to nominate a portion of the USB topology to be transferred to the control of a peripheral driver or function driver. This nomination process generates a token that is associated with the nominated portion. The token is passed by the Hub Driver to the peripheral driver or function driver. The peripheral driver or function driver then uses the token to claim control over the nominated portion of the USB topology. The token can subsequently be transferred to other software entities as appropriate.
