Common Issues

-Corsair K55 Keyboard Disconnects
  • This is a known issue and a fix is being worked on. [Main Thread]
  • Try setting the lighting to high.
  • PM Corsair James for a beta firmware build.

-Problems with the USB Passthrough
  • Make sure both USB ports are plugged in. The pass through will not work without both ends plugged in.
  • Plug the USB port with the keyboard into the higher speed port.
  • Pass through will run at 2.0 speeds regardless of the ports used.

-Problems with Spilling Liquids on New Keyboard
  • Your warranty is voided, so if you need to open the keyboard to clean it do so.
  • Soak the keyboard in 70-99% isopropyl alcohol for 1 mins.
  • Wipe any remaining residue with a cloth.
  • Consider Investing in a Might Mug* [Spill proof mug, or so they say]
*Corsair does not endorse this product in any way, shape or form. Neither Corsair nor I am responsible for drinks spilled from the Might Mug.

-Problems with LEDs not Displaying the Correct Color
  • Contact Corsair Support ask for a hard firmware reset.
  • If that does not work RMA the keyboard with Corsair or exchange it with your reseller.

-Problems with Key Chatter, Key Double Typing
  • Confirm that you have this issue using Switch Hitter.
  • Try a different polling rate which can be adjusted using the switch in the back.
  • Try blowing some compressed air into the faulty key switch.
  • If that does not work RMA the keyboard with Corsair or exchange it with your reseller.

-Problems with Keys Outputting Random Letter's
  • Try the keyboard with and without CUE running.
  • Try the keyboard in another computer.
  • If that does not work RMA the keyboard with Corsair or exchange it with your reseller.

-Problems with Finding Cherry MX Blue RGB Keyboards
  • Stop looking, a lot of the ones on 3rd party sites are extremely overpriced. And you will not get a warranty if they are not an authorized reseller.
  • Corsair is only releasing MX Blue RGB keyboards in small batches due to problems with the Switches
  • This is a Cherry problem, not a Corsair problem. Contact Cherry.

-Problems with LED Flickering
  • Turn off 16.8 million color mode for older devices.
  • Update chipset and USB controller drivers. Update the BIOS. (3rd party USB controllers are known to cause flickering due to dropping packets. There is nothing Corsair can do to fix that. It is high recommended you download the latest drivers for the 3rd party controller and avoid using the basic drivers provided by Windows)
  • Check your logs for dropped packets. This indicates a USB controller issue. C:\Users\(your username)\AppData\Local\Corsair\CUE\logs

-Problems with Macro Execution Being Unavailable
  • Repair CUE with the installer. Please make sure you use the same installer as your CUE build.
  • Check for BIOS, chipset, and USB controller updates.
  • Delete the C:\Users\zhere\AppData\Roaming\Corsair\CUE folder.
  • Uninstall CUE, scan your registry with CCleaner or IObit. Restart and reinstall CUE.
  • Upgrade from Windows 7... [Window 7 Fix]

-Problems with Slow Special Charter Input
  • Check for BIOS, chipset, and USB controller updates.
  • Uninstall CUE, scan your registry with CCleaner or IObit. Restart and reinstall CUE.
  • Remove Asus GPU Tweak II
