| Subject: ALSA: usb-audio: Add delay quirk for all Logitech USB devices |
| |
| From: Joakim Tjernlund <joakim.tjernlund@infinera.com> |
| |
| 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. |
