I know this no_reconnect problem. But haven't found proper correction 
yet. Looks like sometimes with some hw / sw configuration it reconnects 
USB-bus after firmware download and sometimes not. When there is 
no_reconnect set it is possible that driver loads twice (two adapters) 
and it causes race condition when two drivers are accessing same hw same 
time and it hangs (remote polling causes hangs very soon after plug).
You can help and test if it is OK set no_reconnect=0 and remove #if 0 
-killed code by changing it to #if 1 in line where is comment "firmware 
is running, reconnect device in the usb bus". This forces AF9015 chipset 
reconnect USB.

There is no debug logs from af9013 demodulator module. You can enable 
logs by modprobe af9013 debug=1. Remember rmmod modules first from 
memory rmmod dvb_usb_af9015 af9013 mt2060 dvb_usb dvb_core

af9013 debug should log rather much useful data when tuning to channel. 
Did you try change GPIO3 as mentioned earlier?
