Hi

I have two MSI Mega Sky 5580 both of them show this behavior, when I try
to use tzap sometimes like 8 of 10 times I get nothing. If I unplug and
insert it again it works for sometime. Does anyone know what I could do
about this. I have tried this patch, it solved some of the problems, but
all of them.

Here are some output from dmesg during boot 

[   40.775768] dvb-usb: found a 'MSI Mega Sky 55801 DVB-T USB2.0' in
