Logitech's guidance for WiLife camera receiver modules recommends a direct connection to the computer in normal use. On some older systems, insufficient USB power can cause intermittent video streaming. The article suggests trying another computer port and temporarily disconnecting other USB devices to help identify that cause.

An externally powered USB hub is a possible remedy for the particular situation described. This is product-specific troubleshooting, rather than a claim that every unstable USB device needs another hub. Establish whether the power load changes the behavior before adding equipment, and keep the camera system's own supported configurations in mind.
