Hi there I had the same problem with my PVR150 card can TSCHAK and the guys helped me out, you need to do the following:
Advanced -> Configuration -> device templates -> Haupage -> pvr-interfaces cards -> Pvr-150
Under the plug&play section
Create a new plug&play device duplicating everything but the Vendor Model ID .
Don't save just yet.
Now goto a console and issue the following commands
1. mysql -uroot pluto_main
2. SELECT VendorModelId FROM PnpQueue WHERE VendorModelId LIKE "4444%" GROUP BY VendorModelId;
Select the result and add it to the "Vendor Model ID" pnp section of the PVR-150 Template, now save.
Still under mysql on the console
3. DELETE FROM PnpQueue WHERE VendorModelId LIKE '4444%';
Reboot and LMCE should detect your card.
