Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

I plugged it into another machine on ubuntu that has been recently updated which leads me to believe this is a bug. Furthermore the keyboard works fine in BIOS, setup and even in the Advanced settings - I can select recovery mode, but as soon as that finishes the keyboard stops working. I have also plugged it into a Windows machine and the keyboard works fine. Not sure if these files will help but here's what I have found: http://pastebin.com/uzSCh8bM - this is a log from the previous boot on the 25th June, on line 1185 the keyboard is registered and detected as the correct make and model. http://pastebin.com/NJEZ8YYt - this is a log from the day it stopped working and there is no trace of "Corsair" , instead at roughly the same time I find the lines on line (1133): Jun 27 02:53:15 jared-MS-7930 kernel: [ 1.153217] usbhid 1-2:1.0: can't add hid device: -22 Jun 27 02:53:15 jared-MS-7930 kernel: [ 1.153221] usbhid: probe of 1-2:1.0 failed with error -22 This error crops up a number of times but I can find little reference to it on the web. Here is an up to date log of me removing my mouse (which works) and plugging the keyboard into the same port: Jul 3 20:08:33 jared-MS-7930 kernel: [66429.129176] usb 1-14: USB disconnect, device number 8 Jul 3 20:08:53 jared-MS-7930 kernel: [66449.334761] usb 1-14: new full-speed USB device number 9 using xhci_hcd Jul 3 20:08:53 jared-MS-7930 kernel: [66449.463930] usb 1-14: New USB device found, idVendor=1b1c, idProduct=1b04 Jul 3 20:08:53 jared-MS-7930 kernel: [66449.463932] usb 1-14: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Jul 3 20:08:53 jared-MS-7930 kernel: [66449.463933] usb 1-14: Product: KBD Boot Loader Jul 3 20:08:53 jared-MS-7930 kernel: [66449.463934] usb 1-14: Manufacturer: EST Jul 3 20:08:53 jared-MS-7930 kernel: [66449.464411] usbhid 1-14:1.0: can't add hid device: -22 Jul 3 20:08:53 jared-MS-7930 kernel: [66449.464416] usbhid: probe of 1-14:1.0 failed with error -22 I've checked the Software Centre History and hadn't updated since the 24th the only packages being: google-chrome-stable (43.0.2357.125-1, 43.0.2357.130-1) flashplugin-installer (11.2.202.466ubuntu0.15.04.1, 11.2.202.468ubuntu0.15.04.1) I understand that this is difficult to reproduce because you require the specific keyboard but I'm willing to dig and investigate if needed.
