superspeed

USB3 SuperSpeed (5Gbps) and SuperSpeedPlus (10Gbps) for FPGAs without external chip: PHY + Device Core in LiteX.

Windows reports High-Speed (480 Mbps) for a USB device negotiated at 10 Gbps - a 20x understatement from the ioctl every USB tool uses - while separately computing a this-could-go-faster bit no UI shows. usbspeed reads both and flags devices running below capability. Zero dependencies, read-only.

Analyze, benchmark and diagnose USB storage devices on Linux: PyQt6 GUI for lsusb -t, hdparm, dd, fio and smartctl, with plain-language results and an illustrated guide to spotting real SuperSpeed (SS) USB 3.x ports. English and Spanish.
