12 .Nd illumos USB Architecture (USBA)
14 USB provides a low-cost means for attaching peripheral devices, including
15 mass-storage devices, keyboards, mice, and printers, to a system.
16 For complete information on the USB architecture, visit the USB website at
19 USBA supports 126 hot-pluggable USB devices per USB bus.
20 The maximum data transfer rate is 5 Gbits (SuperSpeed USB 3.0), 480 Mbits (high
21 speed USB 2.0), 12 Mbits (full speed USB 1.x), or 1.5 Mbits (low speed USB 1.x).
