No, I don't use usb keyboard, just trying to figure out what could go 

There is a module "usb_keyboard.mod" in grub2 at /boot/grub/ and I 
thought it may be relevant to your problem. It is supposed to enable usb 
keyboard functions for grub. To enable this, a line "insmod 
usb_keyboard" is added at the grub entry.

I had also asked you to wait for 45 secs because some time back, in some 
bios, grub is too quick to jump to boot usb disks when the bios has not 
detected the usb devices yet causing failures in boot. To circumvent 
this, grub put in a delay (called rootdelay and rootwait) automatically 
for booting usb devices. The delay at my computer is 35 secs and I've 
heard others reporting 40 secs.

But sorry to hear it doesn't work out for you.
