Hello,

first thanks for the quirks-table.h patch.
I got it working with some restrictions under 3.13/3.14 vanilla kernel.

The card works fine, after disabling USB 3.0 (Lenovo T440s).
I can set samplerates up to 192khz with 512 Frames
using jack.

With USB 3.0 i can only set samplerates up to 48khz
and get multiple errormessages like:

[ 18.950994] 6:2:1: cannot get freq at ep 0x86
[ 142.670841] retire_capture_urb: 911 callbacks suppressed

After a while the card stops working and jack crashes.

I would really like to help, making full linux support for this device
happen.
I can provide more info if needed.

Cheers,
Christian
