Hi Thierry,

Thank you for the quick reply.
I should have looked in dmesg before...
Checking dmesg before I used tzap shows a problem. dvb-usb: recv bulk 
message failed: -110

**** Extract of dmesg ****

No more messages in dmesg.

I shut down the PC, removed all power, unplugged the CinergyT2s, gave it 
twenty seconds and powered back up.
Once it had booted I plugged in one of the devices and the dmesg output 
below.

Cannot tzap or scan.

With the old version of the driver I don't have any trouble at all.

Hope this helps.
