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?

What kind of audio does this UMTS stick have?

The lsusb output shows that these are bulk endpoints. The snd-usb-audio
driver is designed for isochronous endpoints; a simple quirk would not
suffice.

How many bytes per second?
Best regards,
Clemens

This is a good question. In Windows you can use the Huawei "Mobile Partner"
software to make voice calls using the UMTS stick. You just start the software
and can dial a phone number from there. Then you can use your Headset and/or
Noteboot Microphone to talk with the other partie.

Ok, thank you for the info.
I did some more tests and have seen that Windows is creating 3 serial ports
(COM15, COM16, COM17) for the UMTS stick. It sends the AT commands to COM17 and
(I believe) receives and sends audio over COM16. It is not possible to send any
AT commands to COM16.
If you create a dialup connection then COM15 will be used for it.
In Linux the option module is also creating 3 serial ports (/dev/ttyUSB0,
/dev/ttyUSB1 and /dev/ttyUSB2).
I have done some small test with some AT commands using Windows and was trying
to get audio to COM16 without the "Mobile Partner" software. But it did not
worked.

Unfortunately I did not had much time to do more detailed test.
I will do some more test and will report this.
Thanks and best regards, Artem
PS: What is a good software for doing USB reverse engineering?
I have seen usb-robot and USB Snoopy on Linux, but USB Snoopy is from the year 2000...

The phone is sending 320 bytes every 20ms. So one second of call is
16000 bytes.
I finally managed to write the captured payload data to a file.
I can playback the audio now using
aplay -r 8000 -c 1 -f S16_LE test.wav
If you send the AT-Command "AT^CVOICE?" to the card then it will answer
with "^CVOICE:0,8000,16,20" it is also possible to change this setting.
So I think that the card should be able to output other audio formats
too (like 3G wideband audio), but I have not tested this command out.
The next thing to do is to find out how to make the UMTS-Card output
sound without using the "Mobile Partner" application.
Regards, Artem
