+title: Bindings for the Microchip USB5744 4-port Hub Controller
+
+description:
+ Microchip’s USB5744 SmartHub™ IC is a 4 port, SuperSpeed (SS)/Hi-Speed (HS),
+ low power, low pin count configurable and fully compliant with the USB 3.1
+ Gen 1 specification. The USB5744 also supports Full Speed (FS) and Low Speed
+ (LS) USB signaling, offering complete coverage of all defined USB operating
+ speeds. The new SuperSpeed hubs operate in parallel with the USB 2.0
+ controller, so 5 Gbps SuperSpeed data transfers are not affected by slower
+ USB 2.0 traffic.
