I've been using TrueCrypt for a long time now, and recently changed it up a bit so I can use a static password on my Yubikey.
I'll type in the first part of my password on my keyboard, and then use slot 2 in my Yubikey. Normally this works fine, but a few times a week it'll just give me a bunch of beeps when I try using my Yubikey and only type half of my password. I'll have to keep trying for 10 minutes to get it to work, rebooting doesn't help at all, and I've tried multiple USB ports as well as unplugging all other devices.
I have a quick video actually showing what happens. Any ideas on what could be happening?
