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?
