New subject: How to unsubscribe (was: Re: Cheap RTL2832U / FC0012 gives "No supported tuner found", ...)

Hi All

I bought a cheap DVB-T stick that was supposed to be a RTL2832U with a 
FC0012 tuner with RTL-SDR support. As might have been expected given the 
price, it doesn't work. The various rtl_ tools all report "No supported 
tuner found", eg rtl_eeprom gives:

...
  Found 1 device(s):
  0:  Generic RTL2832U OEM

 Using device 0: Generic RTL2832U OEM
 No supported tuner found
 Enabled direct sampling mode, input 1

 Current configuration:

The vendor did give me a full refund suspiciously quickly, so clearly the 
lack of advertised RTL-SDR compatibility is well known to them!

I then took the cover off, and it does have a chip that's labelled 
RTL2832U, plus another similar sized one I can't read the label of.

After a bit of searching, I found this old post with a patch to list all 
the I2C devices:
https://www.mail-archive.com/osmocom-sdr@lists.osmocom.org/msg00454.html

That reports:

...
  I2C devices found:
 20 a0 a2 
So there is something working there, but I'm not sure if it's enough...

Is there any hope for this stick? And if so, what would my next steps be?

Thanks
Nick
