Grub menu hangs on down arrow press with USB keyboard on cold boot

Bug Description

I installed Windows 8.1 64-bit, then installed Ubuntu 15.04 bit, both in UEFI mode.

When booting, I am presented with the usual GRUB menu, with Ubuntu preselected at the top. If I press enter, Ubuntu loads. If I press arrow down (just once) to move down the menu toward the Windows entry, the highlighted entry skips rapidly to the bottom of the list and GRUB hangs and becomes completely non-responsive. Cycling the power or pressing reset is required.

This only happens on a cold boot, i.e. if the computer was off prior to going to the GRUB menu. If I get to the GRUB menu via pressing the "reset" button, or booting into Ubuntu and choosing "restart", the arrow keys work fine in the GRUB menu.

In addition, this bug only occurs with my USB keyboard (Logitech K120), not with my PS/2 keyboard (Logitech Deluxe 250). Trying different USB ports doesn't help.


What happened: GRUB hangs if I press cursor down when using a USB keyboard after a cold boot
What should happen: I should be able to use arrow down to move down the GRUB boot menu to the entry I require
To reproduce: Install Windows 8, then install Ubuntu 15.04. Turn off power. Turn on power, boot computer, at GRUB menu press arrow down.

Presumably all hardware info is attached to report, but just to be sure: I'm trying to boot off a GPT partitioned 500GB SSD, and have a GA-Z97-D3H motherboard.

If you need any further information, just ask!

Here are the GRUB configuration files from /etc/grub.d

Further information: This bug is present regardless of the "Legacy USB devices" setting in the UEFI menu. I've tried "Disabled", "Enabled" and "Auto" with no luck.

I'm not quite sure why this would happen. I also use a USB keyboard, without seeing this issue.

Does the same happen if you use a different USB keyboard, assuming you can have access to another?

Hi Mathieu,

Okay, I tried another USB keyboard (an Acer of some type) and the problem is still present.

So it does look like a USB problem of some sort, rather than a problem with the specific keyboard I was using.

Been facing this issue for a while myself. I have Ubuntu and Windows on two different hdds and used bit repair to make sure Grub was setup well.
But now it just hangs when I try to select any OS part from Ununtu

Not sure if it is the same issue, but sounds very similar.

Situation: GRUB freezes on my laptop at countdown 10 with not ability to move anything. Currently, this happens everytime my external keyboard is attached.

Equipment: HP X360 i7 configured dual boot. USB 3.1 (USB-A), USB 3.1 (USB-C) and Thunderbolt (USB-C). UEFI Boot.

This is an issue because I want to leave my computer docked and survive a reboot without having to unplug the keyboard all the time. I've googled solutions and "legacy boot" would disable my installed OSs. There is not bios option for "legacy USB" support and none of the GRUB-2 configurations to enable USB, usb-keyboard, etc... have worked.

MY KEYBOARD works before and after grub.... meaning, that at power-on, I can press F10 on usb-keyboard and get to BIOS. Plugging in the keyboard after GRUB boot, keyboard works.

I have tried three separate keyboard... all of which I know are working.
