K90 keyboard not working at all....

so.. i plugged it in without drivers, and software... they keyboard lit up beautifully and the media keys worked fine.

i realise im gonna have to download the software anyway, to get the G keys to work. so i go the the website and download it. First, i install the firmware, click the update button, (while this happens, backlight goes off) wait till its finished, says updated successfully. Then i install the software.

Ok, so backlight hasnt come back on, media keys dont work. restart computer, still no backlight and media keys. uninstall, reinstall drivers. No luck. I go back to the firmware, to which it now says "Cannot open USB device, please reinstall driver!)

Gone into the driver location, installed the drivers, still no luck. In Device Manager, there is an unknown device, i let it search online for the correct drivers AND manually set it where to search. I have also tried it on a different computer, and it still will not work. Am i doing something stupid or is this keyboard not working within the 10 minutes i have had it??

Try re-running the firmware update... maybe it glitched.

Solved - After disconnecting, reconnecting, and numerous times reinstalling, it was indeed the firmware and the program that bugged... but it finally decided to recognise the device and now works....

doesnt bode well for the rest of the software...

I have the same problem with my K90. Please explain in more detial how you got yours to work.

I would hate to have and RMA the keyboard after the first day, just because of some buggy software that works 10% of the time.

It sounds like your firmware was corrupted, or your system had an issue during the update. I'm glad your keyboard is now working. I would of suggested an RMA for your unit.

This problem actually happened to me before. After a firmware reflash, my keyboard backlight also
stopped working and the media keys were not functioning.

I was really afraid I had to send in my keyboard until I was able to stumble upon this fix.

I notice that whenever I plugged in my keyboard, windows would reinstall keyboard drivers and whenever it was finished,
I would see on the bottom right corner of my screen "USB input device installed."
The corsair firmware utility would never recognize my keyboard whenever my keyboard was installed as only an
"input device" and I would get an error message "cannot open usb device, please reinstall driver."
After replugging in my keyboard like around 20 times, my keyboard was finally recognized and installed by windows as a "corsair keyboard."
Miraculously, the firmware update was also able to work its magic on my keyboard and I was able to regain my backlight and media keys.

I hope this post helps out other people with similar problems on this forum.
I don't know if this keyboard has problems that has to be fixed through its hardware or whether the firmware update was simply buggy,
but this problem can be fixed without a RMA if you guys just take the time to test out all your ports.

p.s. my computer has like 15 usb slots so I just plugged the keyboard into each port until it was finally recognized.

I think this is more of an issue with Windows 7.
The USB drivers sometimes don't load up for whatever reason.
I had a phone which stuffed up during an update because the USB driver wouldn't initiate itself or something (code 10). Plugging the usb cable into a different USB port worked eventually.

Thank you guys for the feedback.

Soo.. my corsair k90 mechanical keyboard was working perfectly upon plugging it in and being recognized (or so I thought until I restarted my computer, this caused a hang in the bios over and over.. figured it out pretty quick though)

initially the volume worked as well as all of the normal keys and lights. I went to go grab the software and install it and the firmware. I installed the software first (not sure why.. this seems backwards) then the firmware. It seemed strange that the firmware may not have been fully completed but I impatiently pushed exit thinking that it was.

Lights were not working. Typing was repeating characters about 13 times ever 3rd punch. No media key functionality.

After punching into Google for an answer I figured I should just try re-installing the firmware after reading this thread .. this time I waited much longer and the little firmware box said it was complete then I exited. I must note that the first attempt to re-install the firmware failed. I did NOT re-plug my keyboard like others.. I just simply ran the software again and it worked.

This fixed all of my issues.

Good luck! Great keyboard. Minor hitch.
