Bug Description

After installing two side-by-side quantal installations with 20120913.1 - amd64+mac desktop on a mac mini, it is impossible to boot to the first quantal installation.

Pressing down arrow key at the grub menu does not change anything and the menu timesout with the default 10 seconds and boots with the latest (second in this case) ubuntu installation.

Can you follow the "Boot options" instructions on the following wiki to enable additional output on boot:

As mentioned on the wiki, it would be great if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand.

The issue is with navigating to the kernel entry that I want to boot. So I could not go pass the step 3 on the above wiki. I am attaching a photo of the grub menu if it helps.

Tried to press 'e' to see if the latest installed kernel boot option could be changed but pressing 'e' does not do anything either

Changed the title of the bug because the late findings indicate that none of the keystrokes are recognized. Even with single boot, having forced the grub menu to be displayed with the GRUB_TIMEOUT= -1, there is no way of getting it boot with any kernel due to not being able to select any kernel. nor being able to hit enter to boot with the defaults one.

I expect this was with GRUB 1.99. Please try GRUB 2.00 in today's images and see whether that helps; there's a decent chance that it will, as EHCI support has been added.

I tried this with today's image, 20120914, with b6565ad153301deb66ed38257ae104fe md5sum and the issue is still there. (with GNU GRUB version 2.00-3ubuntu1)

This happens in precise as well, and I've tried the one promising-looking post-2.00 upstream patch (r4559) with no luck. That means that it's not a regression, and is likely a long-standing lack of upstream support for some particular USB device. We are unlikely going to be able to fix this for quantal; I expect a GRUB developer needs to get their hands on an affected system when they have a spare day or two. Thus, tagging rls-q-notfixing.
