From: Joakim Tjernlund <joakim.tjernlund@xxxxxxxxxxxx> commit 54a2a3898f469a915510038fe84ef4f083131d3e upstream. Found one more Logitech device, BCC950 ConferenceCam, which needs the same delay here. This makes 3 out of 3 devices I have tried. Therefore, add a delay for all Logitech devices as it does not hurt.
