USB hub apparatus supporting multiple high speed devices and a single super speed device
Abstract:
Hub apparatus that supports multiple high speed devices and a super speed device. The hub apparatus may include at least one upstream port for coupling to a host device and at least one downstream port for coupling to at least one downstream device. The hub apparatus may further include an embedded device as well as an internal hub coupled to the upstream port, the embedded device, and the at least one downstream port. The internal hub may be configured to provide a connection between the host device and the embedded device at a first speed (e.g., USB high speed). However, when supported by the host device, the embedded device may communicate with the host device at a higher speed than the first speed (e.g., USB super speed), e.g., without using the internal hub.
