System and method for direct device communication with diagnostics and provisioning

A system comprising:

• a host system comprising a processor, a memory electrically coupled to the processor, a storage device coupled to the processor, a user interface electrically coupled to the processor, and a USB port connection coupled to the processor, wherein the memory is further configured with software that when executed performs the steps of:
• electrically connecting a mobile device to a USB port of the host system, the electrical connection further comprising a variable resistance device coupled between the USB port and the mobile device;
• uniquely identifying the USB port and a type of the mobile device attached to the USB port;
• adjusting electrical performance of the USB port based on identified device type and desired function;
• identifying a current state of the mobile device;
• establishing a serial connection between the mobile device and the host system;
• and
• performing diagnostics and device provisioning functions for the mobile device.
