After downloading and installing the new firmware and Cue updates, My Scimitar doesn't act buggy anymore. It seems as though everything with the Scimitar is fine now. The scimitar no longer loses left button functionality with the DPI setting problem. That is fixed. However, some of my Scimitar profiles in Cue have gone a little buggy. The main profile has DPI color and light settings available and functional, where the sub profiles have lost their ability to display DPI lights and colors. Also, My K95 RGB sometimes will not type after a fresh system restart. I have to totally power the system down and restart for the typing to come back on my K95 RGB. Both of these new problems appeared after the update that fixed the buggy Scimitar performance that everyone was talking about in this post. Thanks Corsair. George Cee :)

Intel i7 4790k 16gb Avexir Blitz DDR3 2400 Asus Maximus VII Motherboard with Z97 chipset NVIDIA GTX-980 Reference Graphics Card Corsair K95 Cherry MX RGB Keyboard (Problems went away after updates) Corsair H2100 Headset (Low Mic volume when recording with NVIDIA Share) Corsair 760T Graphite Case (No Problems) Corsair AX860i Power Supply (No Problems) Corsair H100i AIO Cooler (No Problems) Corsair Scimitar Mouse (Corsair M65 RGB being shipped to RMA) I am having the same problems with my Scimitar. The mouse button stops working, the cursor gets choppy & laggy, the RGB Colors freeze. I am using the latest firmware and latest Cue software. It happens 4-5 times per day. It's extremely annoying. Especially when I'm in the middle of a very intense Mechwarrior Online match! This has made me LOSE! The only fix is to unplug the mouse and then plug it back in. I thought it might be the mouse so I went back to Best Buy and exchanged it. Same thing. The people at Best Buy were very nice and exchanged it immediately. I bought the Scimitar to replace the defective Corssair M65 RGB that I have to ship back to Corsair RMA. My K95 RGB Cherry MX Red keyboard also had teething problems when I first bought it and was eventually fixed through the various Corsair updates. My Corsair H2100 Wireless Headset also has problems. I am seriously thinking of returning the mouse instead of waiting for Corsair to fix the problem and then Putting my perfect condition K95 rgb Keyboard on EBAY. For such expensive stuff, the corsair stuff looks good but it's very buggy. We shouldn't be experiencing these types of problems when spending TOP DOLLAR money for premium Mice and Keyboards. My friends think I'm crazy for spending so much on Corsair gaming stuff. They all use Roccat, RAZR and Logitech with no problems at all! Not all is bad from Corsair. My Corsair cases, power supplies, and liquid coolers are all perfect without a problem. George C

I appreciate everyones input in this matter. Stevvie and Remilton both have very good points they made. So far, So good. I'm plugged into the powered USB hub and in 3 weeks I have only had 1 keyboard freeze. Maybe when I upgrade to a new ASUS gaming motherboard with more stable USB power, I will not need to use the hub anymore. I guess we'll see what happens. Have a great evening.

I'm glad that worked for you. It seems like powered USB hubs are the way to go.

I have a really nice motherboard. It's ASRock Z87 Extreme 3 and I am sad to report that's it's USB ports don't play well with my Corsair K95 RGB. I had to resort to using a powered USB hub. You'll need at least 500ma per USB port on a powerfed USB hub to get it operational without freezing. :)

It's about 2 days for me since I hooked up the K95 RGB keyboard to my powered USB hub. Still no freezing or any problems whatsoever. I guess I was lucky. I hope everyone on the forum has positive luck with their RGB keyboards as well. It sucks that you have to buy a USB 3.0 card or high quality powered USB hub to get this keyboard to work without freezing up. I might still return my keyboard & mouse. Not happy at all with the headache Corsair. I have friends with the RAZR products and they have no issues.

Are you using a powered USB hub?

Just like everyone else on the Forum, the functions & lights would freeze up after 5-30 minutes of use. I tried everything that people suggested here on the forum. I plugged into 2 USB 2.0 ports on my computer in different orders, I plugged into 1 USB 3.0 and then I plugged into 2 USB 3.0 ports. I tried every possible combination and nothing worked. I tried every port, etc.. I uninstalled the Corsair Software and totally removed my Corsair M65 RGB mouse and K95 RGB keyboard from my system. I then reinstalled everything and made sure that everything was up to date and correct. I started to think that it was a problem with my USB ports on my computer. I have an ASRock Z87 Extreme 3 motherboard with an Intel i74770K Processor. I decided to take the plunge and update the BIOS on my motherboard to the latest version. Same thing, after a few minutes of serious gaming, the keyboard froze again. I was pretty mad! $189 and it freezes!!!! Not happy. I settled on the fact that if I wanted to keep the keyboard and not return it to Best Buy, then I would just have to get used to flipping the Bios USB Polling rate switch on the back of the keyboard to reset it when this would happen. Since it was only a few days since I picked it up at Best Buy, I was really leaning toward just returning the keyboard and getting a Razr Chroma RGB keyboard. I would also return the Corsair M65 RGB mouse that I bought from Microcenter and get a RAZR Chroma Epic mouse so the keyboard and mouse match. This morning, I was reorganizing my cables and doing a little gaming system reorganization. I plugged both K95 RGB USB plugs into my powered USB Hub and the keyboard does NOT freeze anymore!!! It's been over 12 hours of extreme system use and there has been no keyboard freezing or any issues whatsoever. I have extensively used the Corsair Utility engine software to create profiles and modes. I have installed all kinds of Profiles from the forums and had some good NON-freezing fun with the K95 RGB keyboard. At first I had both USB plugs from the K95 RGB plugged into my powered USB hub, then I unplugged 1 and left only the USB Plug with the keyboard icon plugged in. The keyboard is solid. No Freezing. My USB hub is a Roccat Apuri Powered Active USB-Hub with mouse bungee. The power adapter that plugs into the hub is a 5.0 V - 2A power adapter. The box states that this hub has 4 x high-speed USB 2.0 ports (480Mbps each). The output power is 4 x 5V and max 500ma per port. The Roccat Apuri is plugged into 1 USB 3.0 port on the back of my computer and the power adapter is plugged into my APC Surge Supressor powerstrip. I am using 3 of the 4 ports right now. I plugged in my Corsair M65 RGB mouse, 1 USB keyboard plug from the K95 RGB keyboard and a Logitech C310 webcam into the Roccat Apuri hub. 1 open port on the USB hub. No Issues, No freezing, everything works great. My theory is that the Corsair K95 RGB keyboard is very power hungry and not very compatible with many of the USB hardware/drivers out in the wild. Plugging into the generic Roccat Apuri powered USB hub and providing a fresh and clean 500ma power flow to the keyboard has turned this thing into a very nice NON-FREEZING keyboard. I theorize the passthrough USB plug from the previous K95 RGB keyboard was probably deleted on the new version due to possible power drain from whatever was plugged into that port. I'm sure that the onboard Panasonic lighting controller and all the LEDS must use more power than standard USB devices. The inability of most standard USB connections to provide strong power to this device must be causing the lockups and freezing that everyone is experiencing. Hopefully Corsair can fix this problem. If not, a powered USB hub powered by least a 5V 2A power supply is sufficient to keep the K95 RGB operating perfectly without freezing. Get the Roccat Apuri. It's really cool looking. George Cee :D:
