[linux-dvb] PCTV452e / S2-3600 displays I2C error

[Neil Sutton]

Hi all,

I'm not entirely sure if this is the correct list, but I compiled the
latest 3.2 RC3 kernel to get native support of my S2-3600 tuner
(s2-liplianin seems to cause trouble with my other tuner).

I enabled the PCTV452e module in the kernel and the device detects ok;

[   12.075239] dvb-usb: found a 'Technotrend TT Connect S2-3600' in warm
state.
[   12.076620] dvb-usb: will pass the complete MPEG2 transport stream to

[   15.356832] usbcore: registered new interface driver dvb_usb_dib0700

But when I try to make any tuning with the device I get no picture and the
following get put to syslog;

The 'URB' errors appear each time the card moves to a new transponder, the
I2C errors appear to be when the card is attempting to lock a channel
within the current transponder.

Does anyone have any thoughts on what might be causing this ? - I've had a
search around but can't really find the problem mentioned anywhere... the
device works fine under the latest liplianin drivers.

Many Thanks
Neil
