K70 RGB no bios boot with rear USB 3.0, but with front!


Recommended Posts



I have a big problem and I hope, you can help me to handle this.


I need often to select the partition to boot over the bios and the K70 RGB works only if I connect it on the front USB 3.0 port, but not with the rear (motherboard). But I need the front port too, so I'm asking you if you know what I can do. Thanks.


The mouse (M95) works with the rear port without issues!

I had the same issue and fixed it by going into the bios and changing a value + saving the change, PC reset and then the keyboard was operational for the OS selection.


Mind you, you will need a second USB keyboard to initiate this change.


Hope this helps,

Ensure that Legacy USB and that Full Initialization of the USB are enabled.


"Legacy USB" and "Full Initialization" are choices right? I've been having the same problem, gets stuck on ASUS BIOS screen then I get a post error. Time to try tonight.
