Fail to open device

[cristian5th]

Hello.

It would seem that this utility stopped working with Catalina. I'm getting an error when trying to open the device:

Logitech Driving Force GT Native mode enabled. ERROR: OpenDevice failed with result: e00002c5

Can this be a permissions issue? Any ideas on how to solve it?

Did you find a solution?

I have the same problem...

Hi @simonaagren99

No solution for me. I ended switching to Windows for gaming and the Driving Force GT works perfectly there.

Regards.

I have exactly the same problem on Catalina. Worked fine on Mojave before.

Can't figure out why IOHIDDeviceOpen doesn't return kIOReturnSuccess. I'd guess it's a permission problem.. I tried adding FreeTheWheel and Terminal to "Input monitoring" under Security & Privacy > Privacy but that didn't fix it.

@jackhumbert Any ideas how to fix this?

@cristian5th @simonaagren99
I found out that it works for me if i don't check (and return) the IOReturn but allways return the kIOReturnSuccess. I changed the Error check in this fork.

Now it works for me again on Catalina with the Driving Force GT wheel! :D

Probably a good idea to improve the error checking here.. Add more cases (more info here: https://github.com/obaby/IOKit/blob/master/IOReturn.h)

Great! Thank you @verberktstan ! You can propose the pull request with your solution.

Hello
I have the deiving force gt and with MacOs Catalina the same error "e00002c5" continues to appear
any new solution?

Anyone has been able to use this for F1 2020 on Mac with Stadia? The steering wheel doesn't seem to be recognised.

You only get a warning, no error. For me the controller actually works after running this. On catalina with the DFGT it works. I get the same message that you posted and the 900* angle works..

[verberktstan]

@ricardosobral This script doesn't make your wheel recognizable, it unlocks the 900* steering. I've only tested it on osx Catalina with the Logitech Driving Force GT (it is recognized even if i dont run the script). Works with the Live For Speed simulator, don't know about F1 2020.

Can anyone confirm whether this works with force feedback, specifically on Catalina? Using a Driving Force GT and have installed the old kext, but doesn't seem to be working.

Also, many thanks for this - aside from FF everything is working great.

I've been using ftw for years. Recently updated to macOS Big Sur, nothing works with my G27 any longer. Please make an update!
