4K webcam - controls and switching - usb c

Hey all,
I run a decent rig and seem to be dropping 4K webcams,
They are running on usb c and have died additional usb c cards with 10gbps,
I have run the Elgato 4K cameras to 10gbps hubs and then back to the pc as they cables done seem to adapt well to volt drop,
I guess my question is are there any decent usb c video mixers/ power units / connectors/ hubs that you could suggest,
I have 2 x Elgato 4k60 on usb c and one insta360 running more stable from usb a and an other usb A 2k webcam and a Q2n-4K
The 2 Elgato are a pain in my ass
Something isn’t right and would like some ideas of how I can get it better however I might take the 4K Elgato out and see how this improves and add the 2 x insta 360s in there.
Any knowledge you can share would be appreciated for these situations.

Hi, decent rig = ? laptop, desktop pc, workstation ? What motherboard/CPU/GPU do you have? What is the resolution of the vMix project and the webcams? Elgato 4K cameras = facecam 4k ? insta 360 link ? In most cases, you should avoid USB hubs, because certain motherboard USB ports often already share same USB bandwidth. To avoid voltage drop, you need USB hubs with an external 12V/2A power supply and a VIA VL822 chip, such as the Delock 64053 https://www.delock.com/p...male.html?setLanguage=enFor PCIe cards with USB ports, each USB port needs to have its own controller : PEXUSB3S44V or P5Q4A-USB-CARD : 4 independent 5 Gbps USB ports on a PCIe 2.0 x4 card with 4 Renesas/NEC µPD720202 controllers (1 per USB port) https://www.startech.com...rds-adapters/pexusb3s44vhttps://www.startech.com...-adapters/p5q4a-usb-cardor for usb 10 gbps : P10Q4C-USB-CARD or P10Q4A-USB-CARD : 4 independent 10 Gbps USB ports on a PCIe 3.0 x4 card with 4 ASMedia ASM3142 controllers (1 per USB port) https://www.startech.com...adapters/p10q4c-usb-cardhttps://www.startech.com...adapters/p10q4a-usb-cardIt is preferable for these PCIe USB cards to be installed in a PCIe slot connected to the CPU lanes. If you have any available PCIe x1 slots (i.e. connected to the chipset), you can use a PCIe controller card with 2x USB 3.0 5G Type A ports, powered, featuring the FL1100 chipset but you’ll need to configure the webcam inputs to MJPG or H.264 and conect only usb 2.0 webcams (insta 360 or zoom q2n) https://www.ebay.co.uk/itm/298705338544For a full-USB configuration, an AMD platform is preferable because some of the motherboard's USB ports are connected directly to the CPU.
