DiRT Rally Pedal issues (not being detected)

[ThugUK]

Been playing DR for some years using my G27 wheel, shifter and pedals without issues.
I bought a SST gearstick a few weeks ago which worked straight away (plugged into USB).
I then bought a Fanatec Handbrake about 1 week ago which again worked great (plugged into USB).

I have today bought a set of Fanatec CSP V3 pedals, connected the handbrake to them and plugged them into USB.
Had a play with Assetto Corsa Competizione and they worked fine (after calibration etc), but didn't check the handbrake to be honest.
Then went to try them out of DR and the pedals and HB are not being recognised.
When I select profiles it shows the G27 and that calibrates and works fine, but I cant get it to 'see' my CSP 30V and HB at all.

Any ideas?
