Embodiments provide the cost savings associated with gang mode power port switching and the reduced stress on USB components and individualized protection of USB ports associated with individual mode power switching. Embodiments utilize a plurality of current measurement units to measure the current drawn by each group of USB ports supported by a switch and further utilize a power port control logic unit to control the switch based on whether the current measurements have exceeded a current limit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"USB power port control","description":"A system, method and device for providing over-current protection to USB ports comprised in a USB hub, whereby a single switch is used to control the power supply to one or more groups of USB ports ba","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9715271","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
