 Modern laptops usually lack options to add more USB controllers. So if you're going to use a laptop for recording with many cameras look for gaming-class products. They often include an additional USB controller and more USB ports than conventional "work-horse" laptops. Besides, due to having a high-performance discrete GPU they can be used for occasional tracking, although employing a desktop GPU for that purpose is a preferred option.

-You can check how many USB 2.0 / 3.0 controllers you have in the “Universal Serial Bus controllers” section in Device Manager. Operating system will display USB 2.0 controllers as ''USB Enhanced Host Controller'' (not to be mistaken with USB 1.0 ''USB Universal Host controller''). USB 3.0 controller usually works in USB 2.0 mode, so it will be represented by 2 items - ''USB 3.0 Host Controller'' and ''USB Enhanced Host Controller''

-You should make sure that you have depth sensors or cameras evenly distributed between available USB 2.0 (or 3.0) controllers. For example, if you have four PS Eye cameras, you should connect two cameras to first controller and two cameras to second controller. (But some USB 3.0 controllers can work with four cameras.) Device Manager usually shows USB cameras as “USB Composite Device” at the “Advanced” tab of USB controller properties. If you have too many cameras connected to single USB 2.0 / 3.0 controller, you should re-plug them to different USB ports.

-If several devices are connected on the USB hub and working in parallel, then the USB bandwidth is shared among the devices. Connecting all cameras via single USB 2.0 hub is OK only for low resolution video recording (320x240). To be able to record video at 640x480 and 60 frames per second, you should avoid connecting more than 2 cameras via single USB 2.0 controller and more than 4 cameras via some models of USB 3.0 controllers.

-If you plan getting an additional USB controller, please be aware of potential problems with USB 2.0 controllers available on the market. Many USB 2.0 controllers are based on defective NEC USB 2.0 chip, not capable of standard USB 2.0 speeds. That's a well-known bug specific only to NEC USB 2.0 chip. By contrast, all NEC USB 3.0 chips are good and do not have this problem.

Besides, due to having a high-performance discrete GPU they can be used for occasional tracking, although employing a desktop GPU for that purpose is a preferred option.
-Some manufacturers sell what they call a "USB 2.0 ExpressCard" controller for laptops. Many of such ExpressCard controllers are in fact internal USB hubs in ExpressCard form factor. That means they do not add actual USB bandwidth to the system. All USB 3.0 ExpressCard are controllers.
+{{Important|Some USB chips have compatibility issues with specific cameras which may result in not detecting cameras, low frame rate, etc. See [[#Known compatibility issues|the next section]] on known issues. When getting a PCIe USB card we strongly recommend to look for one based on a NEC/Renesas USB 3.0 chip. It has the best compatibility we've seen so far across various models of cameras and depth sensors.}}
-If you plan getting additional high-speed USB controller, we strongly recommend that you get a USB 3.0 controller, just to be on the safe side.
+Sometimes an USB controllers provides less USB ports than the number of cameras it can handle. For instance, when using RGB cameras with a laptop or a multi-chip PCIe USB card. In this case you can use an ''USB hub'' to increase the number of USB ports and use the full bandwidth of an USB controller. Note that a hub ''is not'' an USB controller, therefore it doesn't increase the number of cameras which can be handled by a controller.
-When setting up a USB 3.0 controller, make sure you configure it to handle USB 2.0 traffic (as opposed to passing USB 2.0 to integrated USB 2.0 controllers in your chipset). There should be a corresponding setting in driver properties or in BIOS.
+{{Important|You can use USB 2.0 or USB 3.0 hubs to connect USB 2.0 cameras. Use only USB 3.0 hubs to connect USB 3.0 cameras. For USB 3.0, prefer ''active'' hubs which use an external power supply.}}

If you need an additional USB controller for connecting specific camera, be sure not to get the one based on incompatible USB chip.
