Abstract

A host device may be enabled to support a plurality of wireless interfaces, wherein some of these interfaces may be utilized to support human interface device (HID) based communication. The host device may be enabled to monitor activity of HID devices based on communications via HID capable wireless interfaces, may predict future use of the HID devices based on the monitoring, and may manage sniff communication that is utilized to track and/or detect activities in the HID devices. The management of the sniff communication may comprise adjusting characteristics of the sniff communication to enable improving throughput of other wireless interfaces available via the host device that may be affected by the sniff communication. The adjustment of the characteristics of sniff communication may comprise adjusting, statically and/or dynamically, length of sniff intervals and/or designating of sniff packets as high priority requests.
