Thank you Le0Kong and ZaltysZ, this is exactly what I have been trying to achieve for my standard X52. It is working perfectly for me in BMS4.32 on Win7 x64.
I found that the main key was in the same place as shown in your reg file but (not suprisingly) I had different VID_#, OEMName, ConfigCLSID and OEMData values so I added the additional keys and values manually.
Thanks again,
Tom
