EFI update, boot from USB?

[yusukeaoki]

Hi guys.

So many of you know we had the EFI firmware update 2.7.

"This update improves the reliability of booting from the network, addresses an issue that can prevent HDCP authentication after a reboot, and resolves an issue with boot device selection when a USB storage device is hot-plugged."

Does this mean we can now boot from USB drives?
I remember when we were able to boot Linux under USB quite a while back.
However recently, Apple stopped that advantage.

But does this mean we can do it again?
Im not entire clear on meaning to this statement.

Thanks in advance.

What this means is that if you remove and/or plug in USB devices while at boot device selection, it should pick up the changes properly.
