Hi, 2 days ago i got my new Corsair K70 RGB. Since that time i'm trying for hours and hours and hours :mad: to get the ****ing device running on my Acer Bigmama Win 7 64bit notebook. I tried USB 3.0 as well as USB 2.0 (yes i plugged in the connectors in the correct order). A boot-beginning the K70 is illuminated red and white which seemed to be a good sign first of all. In grubs OS-Choice the K70 can be used to select the windows 7 entry. But when Windows is up and CUE 1.13.36 is started after short time the CUE-Message "no device detected" is shown. The keyboard is illuminated yet, but doesn't accept any keys. I did as in http://forum.corsair.com/v3/showthread.php?t=138472 described with no success 1. Restarting CUE. => no effect 2. Try a different polling rate which can be adjusted using the switch in the back. => no effect on all polling rates 3. Use a different USB port or configuration. Remember if you are using USB 2.0 plug the one with the arrows in first followed by the one with the keyboard. => no effect 4. Try running CUE as an Admin. => no effect 5. Removing device from Devices Manager. Remove all HID along with all keyboard or mouse devices, depending on your case. Restart your computer. => no effect 6. Make sure the device is not disabled under Devices and Printers => The Corsair composite input device (what ever this is) is installed => the device manager shows a corsair K70 RGB Gaming Keyboard icon with an yellow attention-sign and "says" the driver for this device wasn't installed (Code 28) (have a look at the attached picture) I also tried several older CUE-versions. Nothing helped. Now i'm frustrated and disappointed. After all the K70-RGB is not the cheapest and i didn't expect so much trouble and lost time with a decent tested device. All helpful hints will be greatly appreciated. Thanks in advance, tos
