USB soundcard UR22 setup with quirks-table.h

[unplugged2]

Hello, I want to connect the Steinberg UR22 usb soundcard to Micro core 6 and I`m stuck.

Downloaded the kernel image "linux-3.16.6-patched.txz" and its config "config-3.16.6-tinycore".
Unpacked the kernel and copied the "config-3.16.6-tinycore" into "/.config".
Edited the quirks-table.h in /sound/usb/ adding the ur22 quirk from here: http://pastebin.com/KwZgRmRV
Then I did "make bzImage" and the kernel compiled fine.
Copied the compiled bzImage onto the USB stick into /boot/vmlinuz. Successfully rebooted.

With the UR22 attached, lsmod shows the snd_usb_audio driver loaded, but dmesg still says "snd-usb-audio: probe of 1-3:1.1 failed with error -5" which, I guess, means that the quirk doesn't work and the device is not recognized. No sound.
Reloading the snd_usb_audio module gives me the same error as above /dmesg/.

I would be greatful for any ideas because at this point I don't know where else to look.
