Hi, My Razer Cynosa V2, which I just purchased less than 3 weeks ago, stopped working, LEDs turned off and keys stopped responding. In Device Manager it is listed as "Unknown USB Device (Device Descriptor Request Failed)" I've tried many solutions to this problem, none of them worked. (Rebooting PC, Updating Driver, Uninstalling Driver, Deleting Device and Reinstalling, plugging keyboard into other USB ports) Hopefully someone can help me. Thanks in advance.

    This error message usually means that the USB controller of the keyboard has gone bad. You may have to send it back for replacement. With all that said, you can try to reset the keyboard following the guide provided below.
    • Unplug the Cynosa V2.
    • Press and hold the Escape button (Esc), Caps Lock (Caps), and Space Bar.
    • Plugin the Cynosa to a USB port
    • Release all keys
    If the problem persists, send me the serial number. *Thread locked to curb the conversation to PMs.
