Like the first-generation Surface Hub, the Hub 2S can be wall-mounted or roller-stand-mounted. The device is available in a 50 in (130 centimetres) and a 85 in (220 centimetres) display size, each with a 120 Hz refresh rate 4K touchscreen with multi-touch and multi-pen capabilities, running the Windows 10 operating system.
It requires a license from Intel. A USB controller using UHCI does little in hardware and requires a software UHCI driver to do much of the work of managing the USB bus. [2] It only supports 32-bit memory addressing, [4] so it requires an IOMMU or a computationally expensive bounce buffer to work with a 64-bit operating system.
For example, a USB 2 PCIe host controller card that presents 4 USB "Standard A" connectors typically presents one 4-port EHCI and two 2-port OHCI controllers to system software. When a high-speed USB device is attached to any of the 4 connectors, the device is managed through one of the 4 root hub ports of the EHCI controller.
USB up to 2.0 allows a host or hub to provide up to 2.5 W to each device, in five discrete steps of 100 mA, and SuperSpeed devices (USB 3.0 and up) allows a host or a hub to provide up to 4.5 W in six steps of 150 mA. USB-C supports high-power devices with up to 7.5 W, in six steps of 250 mA. Full-featured USB-C can support up to 15 W.

A USB packet begins with an 8-bit synchronization sequence, 00000001₂. That is, after the initial idle state J, the data lines toggle KJKJKJKK. The final 1 bit (repeated K state) marks the end of the sync pattern and the beginning of the USB frame. For high-bandwidth USB, the packet begins with a 32-bit synchronization sequence. End of Packet ...
