Can I connect multiple U-TAPs to my computer and communicate with multiple capture applications at the same time?

Yes, you can connect multiple U-TAPs to the same CPU using the built-in USB ports! Attaching multiple U-TAPs to a single system, on the other hand, may have an effect on the expected frame rate of incoming video, depending on the CPU, RAM, and so on. If you're going to do this, prepare to test and fine-tune your setup. Compare different host computers and USB port combinations to see which produces the best results. Be aware that on some laptops, a portion (or possibly all) of the USB ports are essentially on a hub, and USB hubs do not always provide adequate power for U-TAP to function reliably.
