Recently upgraded my setup from two to four sensors. I'm using 15 foot active USB 3.0 extender cables for the back sensors. This then equates to 26 feet total(cables attached to sensors is 11 feet I believe?). My two front sensors are straight to my computer. I'm having some jumping issues with tracking in all situations. I'm wondering with the mismatch in cable length if this is causing timing issues?
The other thing is I only have two USB 3.0 ports on my laptop and 1 USB 2.0. So in addition to the cabling described above, the left front and left rear sensor are attached to an active(plugged in) hub which then plugs into my one USB 3.0 port and the right does the same respectively. I'm suspecting I may not have enough band width to run 4 sensors. I don't have anything else plugged into the USB 3.0 ports that the sensors are plugged into. My USB 2.0 also has an active HUB with 4 devices plugged into it.
I presume by active hubs you mean these are powered hubs, right? Overall, sounds like a usb 3.0 bandwidth issue,
If I were you I would try moving at least 2 of your sensors (maybe even all 4 of them?) to the powered usb 2.0 hub and see if this works better.

Can you try with 3 sensors? 4 sensors is technically supported but may not be a better experience than 3, while adding in complications. Also, USB 2.0 is better when using extensions.
