boot single mode usb keyboard does not work at console

i am using a dell USB keyboard model RT7D50, it is an older style, have never had a problem with them regarding compatibility as a usb device.
These are those dell keyboards used everywhere.

when I boot SLES 11.4 via EFI, as a boot option where it gives you the 7 second delay I do

elilo SLES11_SP4_1 single

the server proceeds to boot up in single user mode and the console screen ends up at

hit Ctrl-D to continue or enter root password

My keyboard does not work so i can do nothing other that pull the power cord and reboot the server.
Can someone help?

Below is from /var/log/boot.omsg
part of which i see on the console screen at the end where it says enter root password but i cannot because keyboard does not work. As far as i can tell, it is recognizing a keyboard is there?

It does mention usb hub, I have tried with just keyboard and mouse plugged directly into usb port without using the hub.

The server only has 2 usb ports on the back which is why i use a little belkin 4-port hub that is powered.
The usb ports on the server are blue, so is that usb3 and could that have something to do with it?
The motherboard is a supermicro X10QRH+

Hi
Is there a BIOS option for Legacy USB, if so set this, but like you indicate it is probably a USB 3.0 issue…

Have a look at this thread and add xhci_hcd as a module loaded on boot;

Else you can add insmod=xhci_hcd to the kernel parameters via yaST Bootloader to see if that helps.
