This means that the i2c client did not ACK the i2c transfer.

Due to the "phenomenons" you are describing, I would suspect the
tda18271 is in

Kworld 340U (1b80:a340) kernel 4.8.0 ERROR: i2c_transfer returned: -6

2017-07-08 Thread Kumar Vivek 
New subscriber and first time poster. I have tried to read most of the
instructions and etiquettes regarding the mailing list but there might
still be some noob mistakes on my part.

I have had this tuner for a while and I used it successfully in 2009
(with help from Markus Rechberger - who provided me with the
appropriate patch). I saw that the patches were included in the kernel
drivers and this was fully supported. I tried to use it again recently
and ran into problems and hence this mail. I have spent days trying to
figure out the problem and have been unsuccessful.

I am using kernel 4.8.0

The variant of this USB ATSC device I have has vid:pid = 1b80:a340 ,
EM2870 USB bridge, lgdt3304 demodulator/Frontend, TDA18271HDC2 tuner.

I loaded the em28xx module with debugging on - including i2c bus scan
and i2c transfer.

This is a bit strange since the tuner TDA18271HDC2 is at 0x60 (7 bit)
or 0xC0 (8 bit) i2c address and usually - i2cbus scan doesn't reveal
the tuner's address.

And then this happens :
