I never had this problem with version 1.2, but I just installed 1.32 today and I can't get my Fanatec CSR clutch to register in controls. I'm on Win 7 64-bit, and CSR firmware 7.5/drivers 1.77. The clutch registers fine in the Fanatec control panel. Once I even did get it to pop in as the -z axis, but to see if it was a fluke, I blew it out of there so I can see what was going on, and have never gotten it back in again since.
What's the trick? Gas pedal works, brake works, all other axes and buttons work fine, but not clutch. I double-click clutch in the menu, then hold the clutch fully depressed, and it just comes up blank (or whatever was in there beforehand, as the case may be)
