k70 rgb Unable to update firmware: No device detected

[Ishigami]

Okay this is driving me crazy, again.

It already hunted me with the old CUE. But I thought I give it another spin with 2.5.66.

 

To no avail.

 

The problem: When I try to update the firmware: I press on "update" and then the keyboard vanishes from CUE and the messages "No device detected" appears and the update fails at 0% right away.

 

Mind you the software is detecting the keyboard just fine when I either reset it by reconnecting the USB connectors or change the BIOS switch position.

 

But dare I press “update”, it is gone...

 

It’s usually connected via USB 2.0.

Seems to make no difference with USB 3.0. Though I only have Asmedia realized USB 3.0 (Asus Rampage IV Black).

Anyway the same result: Keyboard works > Update > Keyboard gone > Update fail.

 

I tried:

Switching USB 2.0 connectors -> No result

Switching to USB 3.0 -> No result

Switching off power saving for USB devices -> No result

This: http://forum.corsair.com/v3/showthread.php?t=154018 -> No result

 

Why is the keyboard working “fine” (except a few keys with wrong colours), is detected and once I hit “update” it goes into hiding?

Not to mention I’m currently writing on it… while it is not detected by CUE…

Contact Corsair Support and ask for a hard firmware reflash. The color problem is usually due to corrupt firmware, which could also cause a firmware update to fail.

Okay created a ticket with support.

Problem got resolved by support.

 

Honestly... Corsair should provide direct download of firmware versions and give instructions of the manual flashing procedure alongside it.

 

It’s so easy… could save some time on support employees.
