Hi Jerry,

first of all, please use standard plain text ASCII emails in this mailing list. I don't need extra big fonts and prefer to choose the size of my fonts by myself and not by a weird HTML email.

At the moment I am collection information about the Broadcom dongles and how to integrate a quirk for them. Please include the output of lsusb for this device.

Regards

Marcel

Hi Jerry,

first of all, please use standard plain text ASCII emails in this mailing list. I don't need extra big fonts and prefer to choose the size of my fonts by myself and not by a weird HTML email.

I saw that an SCO MTU: 16:0 should work for audio. What about an SCO MTU: 64: 0 - will that work?

At the moment I am collection information about the Broadcom dongles and how to integrate a quirk for them. Please include the output of lsusb for this device.

Regards

Marcel
