Details:

The keyboard key mapping is wrong on a 'Genius' multimedia USB keyboard. The
<arrow-up> and <arrow-down> keys are mapped to <p> and <n>. The <enter> key is
correct.
I've already tried insmod usb, usb-keyboard. ahci, ohci, ehci in various
combinations (some lead to freezes due to connected usb hdds)without success.

Tested on:
GRUB 2.02 (Linux Mint "Tara" 64bit)
GRUB 2.01beta (Linux Mint "Sylvia" 64bit)
Sandy Bridge (H67 or P67 chipset) on Medion MS-7707 OEM mainboard
BIOS is EFI capable but system runs on legacy BIOS/MBR.
Disabling "legacy USB" in BIOS disables the keyboard completely in GRUB.
Could not check other USB ports yet.

Keyboard mapping works properly in BIOS and Linux. I can provide more output
(lsusb, dmesg..) if needed. I'm not at the target system atm.

Any chance to enforce a different key mapping?
