I have 16 Canon 700D DSLR cameras in the array, and setup a host PC based on INTEL X99 platform that have many USB 3.0 ports. the host can connect to only 4 cameras total at USB 3.0 port, or 7 cameras total at USB 2.0 port. There have 8 cameras connect to 1 USB 3.0 HUB. And 2 USB HUBs are connect to PC's USB 3.0 port or 2.0 port. When I add 5th or 9th camera to the system, windows was poped up some message like" too many USB devices.....".
The motherboard is from GIGABYE, X99-UD4, appearenlly it's a high-end model, but the USB limitation seems no way through..
So anyone know the solution about this issue? Like add USB expansion card or insall some kind of utility tool can fix it?
