Hello,

i am wondering if it is possible to write a quirk in usbquirks.h for a Huawei
K3715 UMTS stick to make the audio interfaces available in linux.

This two interfaces are used for audio (I have sniffed in Windows):

bEndpointAddress     0x83  EP 3 IN
bEndpointAddress     0x02  EP 2 OUT

I have attached a lsusb -vv.

The payload of this interfaces is 320 bytes. Here is an example payload data.
What kind of audio could this be?
