I wonder where you got that impression from; I'm have not seen any

I know of one issue with the pkgsrc libusb1 that could potentially be
the cause.  Could you try rebuilding the libusb1 package with this
patch?

  https://gson.org/netbsd/bugs/libusb1/20220123.patch

Also, please file a PR and include the dmesg or at least the parts
related to USB controllers, hubs, and the camera.
