Most PC manufacturers label each USB port using the logo for USB type [..] the USB 2.0 logo is a trident, while the USB 3.0 logo is a similar trident with the letters 'SS' (which stands for SuperSpeed) attached.
These firmware updates resolve the following issues related to the USB 3.0 ports on these boards: • BIOS and operating system do not detect devices attached to the USB 3.0 ports. • System hangs on POST code 58 for one minute if any device is attached to USB 3.0 ports, and then continues the boot process. • In Device Manager, the Renesas* USB 3.0 eXtensible Host Controller is shown with a yellow bang and the error message 'Windows has stopped this device because it has reported problems. Code 43'.
USB 3.0 includes a variant of the Standard-B connectors which has two additional conductors to provide power to USB adapters. Image courtesy of USB Implementers Forum
As measured by the Ellisys USB Explorer Protocol Analyzer, the IP realized 10 Gbps USB 3.1 effective data rates of more than 900 MBps between two Synopsys HAPS-70 FPGA-based prototyping systems while using backward compatible USB connectors, cables and software.
