Did a git bisect. The last patch where the bug doesn't occur is this
changeset:
em28xx: add module parameter for selection of the preferred USB
transfer type
That means that this changeset broke it:
em28xx: use common urb data copying function for vbi and non-vbi devices
I didn't test them with my Silvercrest webcam yet.
I hope that helps.
