Comment 3 for bug 1448519

I can confirm that this bug exists, using a Logitech K330 wireless keyboard and a Logitech M215 wireless mouse (part of the same wireless keyboard/mouse package of course). Under 14.04.2LTS and 14.10, there's no problem. In 15.04 I can boot up to the point that you have to enter the password to decrypt the hard drive, then it accepts no input. I had to plug in a wired keyboard to be able to type, which seems to work fine. The wireless keyboard and mouse work perfectly once past the LUKS password entry screen, but AT the entry screen you can't type a thing.
