k90 hardware playback grayed-out


Recommended Posts

What does the information screen say? Click the i at the top right hand corner.

Latest BIOS and drivers?

Tried a different USB port?

Check Device Manager and see if there are any errors listed under the K90.



USB Keyboard:

VID: 0x1B1C

PID: 0x1B02

Manufacturer: Corsair

Product: Corsair Vengeance K90 Keyboard

Firmware: NA

Windows: Windows 7 Home Premium 64 bit


I've tried to reinstall the firmware a couple of times using different USB 2.0 ports and I haven't had any luck. I have set my usb selective suspend to disabled.


I ran the profiler in admin mode and I was able to check the Hardware playback box and the click upload to k90 button but the G keys appear to be non-functional (even in software mode).
