Subject: [PATCH] ALSA: usb-audio: Add delay quirk for all Logitech USB devices
Git-commit: 54a2a3898f469a915510038fe84ef4f083131d3e
Patch-mainline: v5.10-rc5
References: git-fixes

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.
