virtual box. Why does webcam interference occur when connecting a usb device?

Question

virtual box

Virtualbox 6.1.10
Guest addition, Extension pack (usb 2.0 plug-in) installed
In the native system, everything works correctly on any port. I don’t understand the logic of the problem, it works through webcam devices, but not through usb. I've tried every usb port on my computer. Webcams should stand up by themselves, without drivers. Webcam, if it's important Atech PK-910P
The essence of the problem is that if you connect it through a webcam device, the Virtual box "device name" is too pale in the device name. I need to either somehow mask this or solve the problem so that the camera works through usb devices. I would be grateful for your help
