I upgraded to Ubuntu 17.04 a couple of weeks ago, and the problem persisted under its version of kernel 4.10.
I just installed all the four packages in the link above, and booted into the new Kernel on Ubuntu 17.04. The problem still persists. This is the output of 'dmesg | grep "usb 3-3"' shortly after boot under this kernel, where usb 3-3 is the USB 3.0 port where the keyboard is plugged in: [ 1.017724] usb 3-3: new full-speed USB device number 2 using xhci_hcd [ 6.369206] usb 3-3: unable to read config index 0 descriptor/all [ 6.369238] usb 3-3: can't read configurations, error -110 [ 6.489148] usb 3-3: new full-speed USB device number 3 using xhci_hcd [ 11.744636] usb 3-3: unable to read config index 0 descriptor/all [ 11.744675] usb 3-3: can't read configurations, error -110 [ 11.864580] usb 3-3: new full-speed USB device number 4 using xhci_hcd [ 17.124668] usb 3-3: unable to read config index 0 descriptor/all [ 17.124705] usb 3-3: can't read configurations, error -110 [ 17.252017] usb 3-3: new full-speed USB device number 5 using xhci_hcd [ 22.495509] usb 3-3: unable to read config index 0 descriptor/all [ 22.495512] usb 3-3: can't read configurations, error -110 [ 39.338187] usb 3-3: new full-speed USB device number 8 using xhci_hcd [ 39.479693] usb 3-3: New USB device found, idVendor=1b1c, idProduct=1b20 [ 39.479695] usb 3-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 39.479696] usb 3-3: Product: Corsair STRAFE RGB Gaming Keyboard [ 39.479696] usb 3-3: Manufacturer: Corsair [ 39.479697] usb 3-3: SerialNumber: 0B03F020AEBD18445619787AF5001946 The last set of messages is where I unplugged the keyboard and plugged back in. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1678477 Title: Kernel has troule recognizing Corsair Strafe RGB keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678477/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
