ow, sorry! I not mentioned that there is no PID of Maschine Mikro (0x1110) in caiaq device list *https://github.com/torvalds/linux/blob/v4.2/sound/usb/caiaq/device.h https://github.com/torvalds/linux/blob/v4.2/sound/usb/caiaq/device.h*
yes there is some endless dump from usbhid but I don't know how to deal with it $sudo usbhid-dump --entity=all --address=1:15 http://pastebin.com/raw.php?i=KC96ERSV (300KiB)
ok, I've tried to extend the driver and end up with following doodad https://github.com/krasnobaev/linux/commits/feature/caiaq-mmikro-1 for every commit I've generated dmesg log *http://pastebin.com/raw.php?i=pJzdAyf4 http://pastebin.com/raw.php?i=pJzdAyf4* $amidi -l have no devices $cat /proc/asound/cards 4 [MaschineMikro ]: snd-usb-caiaq - Maschine Mikro Native Instruments Maschine Mikro (usb-0000:00:02.1-8) $cat /proc/asound/devices 24: [ 4] : control $cat /proc/asound/oss/sndstat Sound Driver:3.8.1a-980706 (ALSA emulation code) Kernel: Linux ***** 3.19.0+ #1 SMP Sun Sep 13 10:44:23 MSK 2015 x86_64 Config options: 0

So, currently customized driver fails (all info in dmesg log) on every usb_submit_urb and usb_set_interface functions, so I've decided to watch wireshark usb logs of windows driver
filtered windows log (usb.transfer_type != 0x01) && (usb.device_address == 3) http://filebin.ca/2G6kerv8x9TD/usbpcap-maschine-mikro-win7-x86-3maschinesoft... RAW http://filebin.ca/2G6g6civjKfI/usbpcap-maschine-mikro-win7-x86-3maschinesoft...
filtered log for custom driver http://filebin.ca/2G6kFZxgTTKR/usbpcap-maschine-mikro-ubuntu15.04-linux3.19-... RAW http://filebin.ca/2G6oNuU6c6b5/usbpcap-maschine-mikro-ubuntu15.04-linux3.19-...
the difference is... - windows driver do not send SET INTERFACE request while native caiaq driver is. - windows driver receives Response and Status on each request while caiaq recieves only Response - windows driver send two GET_REPORT with wValues: 0x03f8 and 0x0101 while caiaq driver sends three GET_REPORT requests with wValues: 0x0101, 0x0120, 0x03f8 - windows send 3 SET_REPORT requests with same wValue 0x03f8 while caiaq driver do not send any SET_REPORT request
I do not know what means these wValues (0x0101, 0x0120, 0x03f8) and how to find out.
Is there probability if linux driver send SET_REPORT requests in the same way as do windows driver - the device will set up correctly? How to send SET REPORT request?
I believe that there is no big difference between Maschine Controller and Maschine Mikro. BUT there is no Maschine Mikro on caiaq portfolio http://caiaq.de/references_en.html

No it's not; the Maschine Mikro is not the same as the Maschine Controller.
As far as I can see from your lsusb output, the Mikro either works as a HID input device, or needs a separate driver. To check the first possibility, try a tool like https://github.com/DIGImend/usbhid-dump.
