APPARATUSES, METHODS, AND SYSTEMS FOR ENABLING HIGHER CURRENT CHARGING OF UNIVERSAL SERIAL BUS (USB) SPECIFICATION REVISION 2.0 (USB 2.0) PORTABLE ELECTRONIC DEVICES FROM USB 3.X HOSTS
APPARATUSES, METHODS, AND SYSTEMS FOR ENABLING HIGHER CURRENT CHARGING OF UNIVERSAL SERIAL BUS (USB) SPECIFICATION REVISION 2.0 (USB 2.0) PORTABLE ELECTRONIC DEVICES FROM USB 3.X HOSTS
Apparatuses, methods, and systems for enabling higher current charging of Universal Serial Bus (USB) Specification Revision 2.0 (USB 2.0) portable electronic devices from USB 3.x hosts are disclosed. In one aspect, a USB 2.0 controller is provided in a USB 2.0 portable device. A USB 3.x controller is provided in a USB 3.x host. The USB 2.0 controller is configured to draw a higher charging current than specified in USB 2.0 for the USB 2.0 portable device over a USB 2.0 cable. In order to draw the higher charging current without violating USB 2.0, the USB 2.0 controller is configured to use one or more reserved elements in an existing USB 2.0 descriptor(s) or bitmap(s) to indicate a higher charging current request from the USB 2.0 controller.
