[linux-uvc-devel] Support for Logitech StreamCam

[Severin K. <sek...@gm...>]

Hello uvc developers,

I hope I am doing this right.
Because of the pandemic, this was the only decent device I got.
I even got a USB type C PCI device for it.

I am not sure that the USB device could be a factor too, with bandwidth

the lshw for it
