Subject: [PATCH 02/14] USB-Audio: Blacklist iec958 for some USB devices
|
|
|
|
Some common USB devices are analog only, so prevent the digital
|
|
devices from being opened. This simplifies probing the device
|
|
in PulseAudio.
|
|
|
|
I have a "Logitech USB Headset" myself, the "Logitech Web Camera"
|
|
was reported by Raymond Yau, and the "Blue Snowball" was reported by
|
|
Andy Whitcroft.
