Xvisio Device and Precautions for Use

Xvisio SDK adapts to all Xvisio devices, but there are some precautions and requirements when using the Xvisio device to the host including all the system platform hosts that the SDK can support:

• USB bandwidth
  Different Xvisio devices have different requirements for the USB bandwidth, and the host needs to be able to meet the corresponding requirements:

  Device	USB Type	Supported Maximum Bandwidth
  SeerSense™ DS80	USB3.1 Gen1	3Gbps
  SeerSense™ XR50	USB2.0	480Mbps
  SeerSense™ XR80	USB3.0	2Gbps
  SeerLens™ One AR Glasses	USB3.0	2Gbps
  SeerLens™ B50R pro AR Glasses	USB3.1 Gen1	3Gbps
  SeerLens™ K40RE AR Glasses	USB3.1 Gen1	3Gbps

Note: When the host cannot meet the maximum bandwidth requirements, it is possible that the frame rate of the device will be affected in different scenarios. Please consult the data sheet of the device for the USB bandwidth corresponding to the specific scenario.

• USB Power Delivery
  Different Xvisio devices have different requirements for USB power supply capacity and the host needs to meet the requirements. Some Xvisio devices include TOF cameras with infrared projectors that periodically emit infrared waves and bring periodic load peaks, so the current of the device The peak value has certain requirements on the USB power supply load capacity of the host:
