Abstract
The disclosure describes a system and method for controlling interfacing parameters for a device when connected to a host. In the system and method, the communications interface is configurable to be in operable connection to a host using a microprocessor in the device having a first bus controller and a second bus controller, the second bus controller external to the microprocessor. The method comprises: establishing an initial connection by the device; conducting negotiations by the device to set a first data transmission rate for the device for the initial connection utilizing a communication bus controller contained in the microprocessor; and after detecting completion of enumeration of the device, re-establishing the connection by the device using the second bus controller in the device that processes the communications at a second transmission rate that is higher than the first data transmission rate.
