ATI shows firmware version of 1.0.2.

I think firmware on my EM7565 is very old and may have issue in upgrading firmware.

Also, I found this:

As described in above, I am able to upgrade to version 1.7.2, but only under Windows. Upgrading in Linux still does not work. But I think it doesn’t matter at this point.
