ow, sorry! I not mentioned that there is no PID of Maschine Mikro (0x1110) in caiaq device list
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
ok, I've tried to extend the driver and end up with following doodad
for every commit I've generated dmesg log
$amidi -l
have no devices
$cat /proc/asound/cards

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)
RAW
filtered log for custom driver
RAW
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

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>.
