SOLVED: The board was shipped without the leonardo bootloader even though it was advertised as such. I solved this by using ESP8266 NodeMCU dev board and flashing a bootloader with it.

I've installed the `arduino` AUR package, added myself to the uucp and lock groups(and tty, since I found that in some other forum issue) and modprobed `cdc_acm`.
After rebooting and plugging the chinese clone into my USB port, this is the output of `dmesg`
[58965.060348] usb 3-2: new full-speed USB device number 32 using xhci_hcd
I can further see this with `lsusb`
Bus 003 Device 032: ID 03eb:2ff4 Atmel Corp. atmega32u4 DFU bootloader
However Arduino IDE is not detecting it at all (greyed out port) - http://i.imgur.com/TiQzA3K.png
Running Arduino IDE with sudo makes no difference at all and there are no errors in the terminal.
I didn't see anything with `journalctl -xe` that was anyhow relevant to the arduino.
EDIT: Also there are only numbered tty's in /dev, except for ttyS0-S3.
EDIT2: Found out how to access the Pro Micro but I still have no idea how to use it within the IDE
