Abstract
An information handling system includes a processor that provides a USB-2 channel and a USB-3 channel to a device. The device provides the USB-2 and -3 channels to selected ports. Each port includes a USB-3 enable setting. When the USB-3 enable setting for each particular USB port is in a first state, the associated device USB-3 channel is active, and when the USB-3 enable setting for each particular USB port is in a second state, the associated device USB-3 channel is inactive. The USB-3 enable setting for at least one of the USB ports is placed into the second state to reduce electromagnetic interference between the associated USB-3 channel and an antenna.
Claims20
An information handling system, comprising:
- a processor to provide a processor USB-2 channel and a processor USB-3 channel;
- a wireless communication interface including an antenna;
- and
- a USB hub device including a plurality of USB ports, each USB port to provide an associated port USB-2 channel and an associated port USB-3 channel, the USB hub device configured to receive the processor USB-2 channel and the processor USB-3 channel, to route the processor USB-2 channel to each of the port USB-2 channels, and to route the processor USB-3 channel to the each enabled port USB-3 channel;
- wherein:
- each USB port includes a USB-3 enable setting, wherein when the USB-3 enable setting for each particular USB port is in a first state, the associated port USB-3 channel is enabled, and wherein when the USB-3 enable setting for each particular USB port is in a second state, the associated port USB-3 channel is disabled;
- and
- the USB-3 enable setting for at least one of the USB ports is placed into the second state to reduce electromagnetic interference between the associated USB-3 channel and the antenna.
A method for reducing electromagnetic interference between a USB-3 channel and an antenna of a wireless communication interface of an information handling system, the method comprising:
- receiving, by a Universal Serial Bus (USB) hub device of the information handling system, a processor USB-2 channel and a processor USB-3 channel from the information handling system, wherein the USB hub device includes a plurality of USB ports, each USB port to provide an associated port USB-2 channel and an associated port USB-3 channel, and wherein each USB port includes a USB-3 enable setting, wherein when the USB-3 enable setting for each particular USB port is in a first state, the associated port USB-3 channel is enabled, and wherein when the USB-3 enable setting for each particular USB port is in a second state, the associated port USB-3 channel is disabled;
- routing, by the USB hub device, the processor USB-2 channel to each of the port USB-2 channels and routing the processor USB-3 channel to each enabled port USB-3 channel;
- and
- placing the USB-3 enable setting for at least one of the USB ports into the second state to reduce the electromagnetic interference between the associated USB-3 channel and the antenna.
An information handling system, comprising:
- a processor to provide a processor USB-2 channel and a processor USB-3 channel;
- a Basic Input/Output System (BIOS) module;
- a Global Positioning System (GPS) interface including a GPS antenna;
- and
- a USB hub device including a plurality of USB ports, each USB port to provide an associated port USB-2 channel and an associated port USB-3 channel, the USB hub device configured to receive the processor USB-2 channel and the processor USB-3 channel and to route the processor USB-2 channel to each of the port USB-2 channels and to route the processor USB-3 channel to each enabled port USB-3 channel;
- wherein:
- each USB port includes a USB-3 enable setting, wherein when the USB-3 enable setting for each particular USB port is in a first state, the associated port USB-3 channel is enabled, and wherein when the USB-3 enable setting for each particular USB port is in a second state, the associated port USB-3 channel is disabled;
- and
- the BIOS module places a USB-3 enable setting for at least one of the USB ports into the second state to reduce electromagnetic interference between the associated USB-3 channel and the GPS antenna.
