iCue Software not recognizing Keyboard after waking from Sleep - Band-Aid

Recommended Posts

Purchased a Corsair K70 LUX RGB keyboard after much research and looking at specs. Have been in IT for a looooong time, so when I got home, ripped it out of box and plugged it in, downloaded latest iCue software and Voila - NOTHING. No pretty lights, no control, just said keyboard not recognized. Unplugged/re-insterted the keyboard from usb connections and now was able to use iCue. Chalked it up to "maybe I should think about reading instructions -Doh".


When I came back a few hours later to play some more, pressed space bar, system resumed from sleep, and Voila- no saved profile, so no pretty colors. Tried started and stopping icue service, but still no love. Unplugging/plug keyboard worked again, but I am thinking "My computer is way under my desk and this is a PITA". Did some research, found that this is a REALLY old issue with the Corsair iCue software and several systems and keyboard and mouse combinations. Things were looking bad. Contacted support, and they sent me firmware to manually flash to keyboard, but even they said it might not work. It didn't. So, my options were to return the keyboard, or make a fix.


I'm too old and tired to go into specific details, and this is not a walk through, someone else can type it all up if they want, but here is the band-aid that I used to make the keyboard work, every time. someone else might have already have found other solution, but I'm too impatient to keep looking, so this is my fix, for me, and only took me 5 minutes to do. YMMV


I have windows 7 64 bit, so I downloaded the "devcon.exe" application for my OS (free from Microsoft), found the name of the device that controls my USB port (in Device manager), wrote a batch file that disables and enables that USB port, then used task scheduler to create 2 tasks, one to run the batch file on every startup, and another to run it after starting from sleep mode.


Now, after about a .5 second delay, the keyboard always is recognized by the iCue software, and lighting/profiles work every time, just as they should, no unplugging/plugging, etc.


Hope this helps someone.


Just for extra info, here is the batch file that resets MY USB port, yours will be different of course.


@echo off

devcon disable "PCI\VEN_10DE&DEV_03F2&SUBSYS_03941025&REV_A3"

devcon enable "PCI\VEN_10DE&DEV_03F2&SUBSYS_03941025&REV_A3"
