System and method to selectively reduce USB-3 interference with wireless communication devices
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.

The information handling system of claim 2 , wherein in reducing the electromagnetic interference between the associated USB-3 channel and the antenna, the information handling system receives a better position indication from the GPS interface than when the USB-3 enable setting for the at least one USB ports is placed into the first state.
4. The information handling system of claim 1 , further comprising:
a Basic Input/Output System (BIOS) module operable to place the USB-3 enable setting into the second state for the at least one USB port.
5. The information handling system of claim 4 , wherein the BIOS module is further operable to provide a user interface to select the at least one USB port.
6. The information handling system of claim 5 , wherein the BIOS module places the USB-3 enable setting into the second state in response to a user input to the user interface.
7. The information handling system of claim 1 , wherein the processor is operable to place the USB-3 enable setting into the second state for the at least one USB port during a run time operation of the information handling system.
8. The information handling system of claim 7 , wherein the processor places the USB-3 enable setting into the second state in response to a user input to processor.
9. The information handling system of claim 1 , further comprising:
an embedded controller operable to place the USB-3 enable setting into the second state for the at least one USB port.
10. 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.
11. The method of claim 10 , wherein the wireless communication interface is a Global Positioning System (GPS) interface.
12. The method of claim 11 , wherein in reducing the electromagnetic interference between the associated USB-3 channel and the antenna, the method further comprises:
receiving, by the information handling system, a better position indication from the GPS interface when the USB-3 enable setting for the at least one USB port is in the second state than when the USB-3 enable setting for the at least one USB ports is placed into the first state.
13. The method of claim 10 , further comprising:
placing, by a Basic Input/Output System (BIOS) module of the information handling system, the USB-3 enable setting into the second state for the at least one USB port.
14. The method of claim 13 , further comprising:
providing, by the BIOS module, a user interface to select the at least one USB port.
15. The method of claim 14 , wherein the BIOS module places the USB-3 enable setting into the second state in response to a user input to the user interface.
16. The method of claim 10 , further comprising:
placing, by the processor, the USB-3 enable setting into the second state for the at least one USB port during a run time operation of the information handling system.
17. The method of claim 16 , further comprising:
receiving, by the processor, a user input, wherein the processor places the USB-3 enable setting into the second state in response to the user input.
18. The method of claim 10 , further comprising:
placing, by an embedded controller of the information handling system, the USB-3 enable setting into the second state for the at least one USB port.
19. 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;
