I noticed that on the main page it says support for the Blackwidow Ultimate 2016 is in progress, so I'm not sure how much to expect; I just got an Ultimate Stealth 2016 keyboard and installed the driver, and when I try to start it, /var/log/upstart/razer_bcd.log contains:
Unknown device, --name=, --path=, or absolute path in /dev/ or /sys expected.
Unknown device, --name=, --path=, or absolute path in /dev/ or /sys expected.
Binding device (*:1532:020[39]*) to hid-generic
At a glance, I can see that in 95-razerkbd.rules, it does not have a line that matches my keyboard; the product ID according to lsusb is 0214.
