Logitech Formula Force Drivers for Windows 10 64 Bit (x64)

Almost 20 years on, the Logitech Wingman Formula Force still works in windows. Released around the time USB was just arriving on the market, these robust wheels date from back in 1998.

Logitech discontinued driver development in 2006, however Saitek did release a 64bit driver based on the Immersion SDK. A primitive Force feedback design by today's standards, but it still works with most modern games.

This driver was adapted by Sly_North from the below Saitek source. 

To breath a new bit of life into the Logitech Wingman Formula Force, here is a Windows 10 Driver (signed) that will permit installation into Win10 x64 bit without the need to disable driver signing.

UPDATE [August 2022] - Ken830 has kindly provided the PIN outs for the DB9 to USB adapter

I measured all the pins of the DB9-to-USB cable... I did not find any connections between pins on the DB9 side -- all were open-circuit, and I checked it twice. 

Here's the pinout: 
    • DB9.1 <=> USB.1 (Vcc) 
    • DB9.5 <=> USB.4 (GND) 
    • DB9.8 <=> USB.3 (D+) 
    • DB9.9 <=> USB.2 (D-) 
    • DB9.Shield <=> USB.Shield

UPDATE [Jan 2020] - This driver no longer installs on fresh Windows 10 OS. This is due to MS changing signing requirements under fresh installs in Windows 10. The below driver is signed with SHA-1, which is no longer trusted, thus not supported in newer releases of Windows 10. I'm looking for a volunteer to re-sign these driver with SHA256 as per Practical Windows Code and Driver Signing

SHA256 ECC4B98757FFBF53501A7D239CE3FA3B4D05B9543F091CA156D9EDE1ED44DB6F

Last version of Logitech Gaming Software (LGS) to support the wheel (Windows XP 32bit)
