Hello list!
I would like inform you (as Tobias Grimm <tobias.gr...@e-tobi.net> he is
the w_scan maintainer for Debian) as suggested to me to look deeper on my
issue so I decided to explain my issue.
Here is some information:
System Machines:
Apple PowerBook G4 32bit PowerPC Laptop
Apple Quad Core G5 64bit PowerPC Tower
On both machines I have the _SAME_ Debian Jessie and the same kernel
version, and the same version of linux-non-free drivers and the DVB API
(from debian repos) for the USB dogle DVB-T I am using.
The G5 Machine has the 64bit version meanwhile the G4 is the 32bit version.
When connecting the USB Dongle on the G4 I have the same messages I got in
the G5 machine:

I wrote to Tobias and he sent me a simple code to check what version is
running on dvb_core DVB-API (the code is in attachment) and it reports:
POWERPC G4:
$ ./getdvbapiversion /dev/dvb/adapter0/frontend0
DVB-API Version from header files: 5.10 (0x050A)
DVB-API Version from frontend /dev/dvb/adapter0/frontend0: 5.10 (0x050A)
POWERPC G5:
$ ./getdvbapiversion /dev/dvb/adapter0/frontend0
DVB-API Version from header files: 5.10 (0x050A)
Could not query API version from the DVB API
It seems in the POWERPC G5 the legacy ioctl to the FE in general works. It
just seems the new
FE_GET/SET_PROPERTY are not accepted.
It is strange, because on POWERPC G4 works.
Some hint, help or clue??
Best Regards,
Gianluca
