Re: AF9015 Dual tuner i2c write failures

I concur.  I have been using Malcolm Priestly's patches with both my
AF9015 dual tuner cards (which are PCI but still look like USB to the
kernel) for a few weeks now and have (finally!) got consistently
perfect recordings in MythTV simultaneously with both tuners on a
card. Malcolm, when do you think you'll submit these patches to the
tree for inclusion?  Is there anything else to test?

I agree about the power cycling.  Every time I reboot I disconnect the
AC supply for 20secs to be sure the cards are power cycled properly -
you do the same thing by pulling out the stick.
