[vdr] Can't write to CI adapter on device 0

Hi.

Lots of posts recently - many of which I've resolved!

The latest -

I've added an Irdeto CI adapter to my TT-1500 Budget card. But I can't decrypt channels, and get the following errors:

In /var/log/messages: Apr 30 19:31:26 media1 vdr: [2774] CAM 1: module present Apr 30 19:31:28 media1 kernel: dvb_ca adapter 0: DVB CAM detected and initialised successfully Apr 30 19:31:28 media1 vdr: [2774] CAM 1: module ready Apr 30 19:31:29 media1 vdr: [2774] ERROR: can't write to CI adapter on device 0: Input/output error

In dmesg: dvb_ca adapter 0: DVB CAM detected and initialised successfully dvb_ca adapter 0: DVB CAM detected and initialised successfully dvb_ca adapter 0: DVB CAM detected and initialised successfully

and in the CAM menu on VDR: 1 CAM present 1 CAM ready 1 CAM present 1 CAM ready (etc)

vdr-1.5.2, v4l-dvb hg snapshot from yesterday.

Any ideas??
