Note that "YUMI" is not the "Universal USB Installer" linked to in $URL and may not be tested.

At any rate this is a bug for releng, but I'm not sure if they can do anything about a third party software failing to boot Gentoo.

Hello,

Sorry,
Now i try to be more precise ...

Here

YUMI – Multiboot USB Creator
< http://www.pendrivelinux.com/yumi-multiboot-usb-creator/ >
< http://www.pendrivelinux.com/downloads/YUMI/YUMI-2.0.1.7.exe >


So, i experienced this <YUMI – Multiboot USB Creator> ,
successfully for : backtrack, kali, linuxmint, knoppix, debian, suse 

So, i try YUMI for gentoo-live.dvd...20140825.iso
under the YUMI's title  (~) 'not listed iso' ( ~ )
and finally, got the grub1 header :


/media/tecb/multiboot/gentoo-x86-amd64-32ul-20140826/boot/grub

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Gentoo x86-amd64 32bit userland' --class gentoo {
  set gfxpayload=keep
  echo "Language: $bootlang"
  echo "Keyboard: $bootkeymap"
  echo 'Loading amd64-nomultilib 3.15.6 kernel'
  linux /isolinux/gentoo root=/dev/ram0 init=/linuxrc aufs looptype=squashfs loop=/image.squashfs cdroot vconsole.keymap=$bootkeymap locale=
  echo 'Loading initial ramdisk ...'
  initrd /isolinux/gentoo.igz
}

menuentry 'Gentoo amd64 multilib' --class gentoo {
  set gfxpayload=keep
  echo "Language: $bootlang"
  echo "Keyboard: $bootkeymap"
  echo 'Loading amd64-nomultilib 3.15.6 kernel'
  linux /isolinux/gentoo64 root=/dev/ram0 init=/linuxrc aufs looptype=squashfs loop=/image.squashfs cdroot vconsole.keymap=$bootkeymap local
  echo 'Loading initial ramdisk ...'
  initrd /isolinux/gentoo64.igz
}


Then, i run menuentry 'Gentoo x86-amd64 32bit userland' ( not 'Gentoo amd64 multilib'),

YUMI starts, 
loads gento's start boot stuff, ... 

then 
Gento.livedvd.usb:boot 's process asks me for locale 
> (en_US) : i enter default's

... then here we are on the spot :


then, Gento.livedvd.usb:boot 's process 

<try to get /dev/sr0> id the cd or the dvd, instead of the usb 
<try to get /dev/sr0> id the cd or the dvd, instead of the usb 

And that's is the question ...

At this stage, this is a info forwarding, -- i am not able figure myself deeper in details where this comes out from ...

If third-party software fails to function, that's not something that Gentoo's RelEng team can fix.

The root cause of this issue is likely the missing USB support in the latest kernels that is causing all the USB issues.
So this is likely another dupe of bug 522176.
