This older MS 3d Pro stick (15 pin D connector) will not work properly on fast CPU systems without a patch that's available from MS's dowload area. Even using the special DLL from MS, my experience with 3 of them was they worked "hit and miss" up to and including my 600 Mhz Intel machine. The symptom was the "not found" error you're experiencing. I used to do a lot of rebooting to try and catch them in a "connected" state.
Once I went to an 866 Mhz and higher, none of them worked at all even with the patch. I finally went out and bought Sidewinder Precision 2 USB version.
Sorry I don't have better information for you.
