I played around with the Cr-48 camera a few weeks ago, and noticed that you can easily upload video to YouTube. Today I noticed it was broken - YouTube said that no camera was detected.
Luckily the fix was only a Google search away. It turns out that on the about:plugins page there are two Flash players shown. Disable the one that has version number 10.2.158.6, path /opt/google/chrome/pepper/libpepflashplayer.so. Reopen the YouTube upload page, and all should be well.
