Dear Maintainer,

I'm using grub2 in association with Windows XP and 7. When booting after a suspend to disk (S4), I am unable to select an Operating System (kernel) because of grub seem not to load a USB-driver for my USB-keyboard. When using a PS2-keyboard everything works fine.

For this reason I have to reset my machine to make the GRUB bootmeny working again.

Therefore I request a review of the code which loads the USB driver in grub and a patch if necessary.

Best regards,
Hans-Peter Teufel

PS: I do not know if this bug is debian-specific or not. Please mark it as upstream if you or someone knows that it is.
PPS: I've already sent a similar bug report to bug-grub@gnu.org on 2014-04-13, without any reaction so far. The bug did not appear in their own BTS yet (as far as I can tell).
