The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. There may be one translator per hub or per port.
The idle line state is when the device is connected to the host with a pull-up on either D+ (for full speed USB 1.x) or D− (for low speed USB 1.x), with transmitter output on both host and device is set to high impedance (hi-Z) (disconnected output). A USB device pulls one of the data lines high with a 1.5 kΩ resistor.
The EHCI dependence on separate host controllers for high-speed USB devices and the group of low-speed and full-speed USB devices results in complex interactions and dependencies between the EHCI and OHCI/UHCI drivers. The xHCI architecture eliminates the need for companion controllers and their separate driver stacks.
Many device interfaces or protocols (e.g., SATA, USB, SAS, PCIe) are used both inside many-device boxes, such as a PC, and one-device-boxes, such as a hard drive enclosure. Accordingly, this page lists both the internal ribbon and external communications cable standards together in one sortable table.
USB 2.0 provides for a maximum cable length of 5 metres (16 ft 5 in) for devices running at high speed (480 Mbit/s). The primary reason for this limit is the maximum allowed round-trip delay of about 1.5 μs. If USB host commands are unanswered by the USB device within the allowed time, the host considers the command lost.

The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...
