I post the saga in case anybody can suggest anything else I should try. This includes various attempts to fix problems which may help other people.
On the day I had set aside to install the '55 mod, suddenly, a Windows notification popped up telling me my G27 was undergoing further configuration. When I next tried to use the wheel it wasn't recognised by GPL. When I plug the usb cable in, the Wheel re-centres, lights come on as per normal start up. Wheel is active (i.e. has resistance to turn it). As soon as I start a game the wheel goes limp and is not detected by the game. Wheel is plugged in to a USB2 port. I have tried plugging in to various other USB2 ports (directly on the PC on through a hub).
I tried uninstalling the Logitech profiler and downloaded the latest 64 bit version (lgs510_x64.exe v5.10.127) from the Logitech site. During the device detection process the above again happens, wheel initialises when I plug it in but then it goes limp as the install tries to detect it. I have also tried tried an older version of the Profiler install (I think the version that I originally installed, still v5.10.127).
So began the internet searching for a solution. Logitech support site, logitech Community, YouTube etc... Amongst the things I have tried are......
1) Logitech WheelDriverCleaner
Disconnect the Gaming wheel from your computer.
Download and save WheelDriverCleaner.exe [http://chilp.it/c09316a] to your desktop
Run the cleaner tool by double clicking the file from your desktop.
Close the cleaner tool dialog box. Reconnect your Gaming wheel to your computer.
2) Updating the device driver manually
After two of many attempts with the WheelDriverCleaner it did result in the Logitech Profiler detecting my wheel as a "Logitech Driving Force Wheel". Can't work out what combination of events got me to that point so I can't repeat it. This is a common issue apparently. Some possible solutions to this can be found at
When I tried these I either get "Windows Encountered a problem installing the drivers" as I try to update the driver. Or if I re-install the Logitech Profiler I go back to square one, the wheel is not detected at all.
3) Stopping the install process part way through and manually installing drivers from from the temp files it creates
Uninstall the G27 and profiler before completing these steps.
Launch lgs510_x64.exe from Logitech drivers.
Don’t click anything in the driver pop-up but just leave it opened
Do a research with CTRL+F and search for the folder 2b-LGS-x64
Open the most recent folder named 2b-LGS-x64 and go to \Common64\Logitech\WMDrivers\
Right-click on wmjoyhid.inf and Install. Don’t accept the reboot. Close all windows.
Close also the driver pop-up and launch again lgs510_x64.exe. Click on next and so on, as usually. This time, the wizard should recognize your G27 as a G27 wheel Smiley Happy
After installing, reboot your PC.
4) removing Logitech HID device drivers from the device manager (including any ghost entries in Device Manager) before rebooting/re-installing Logitech Profiler.
Remove the current version of Logitech Gaming Software installed on your computer.
Launch command prompt (Start > type cmd in the search box). Command box will appear.
Run this command: set devmgr_show_nonpresent_devices=1.
Then, run the command devmgmt.msc to start Device Manager from the Command Prompt.
Once the Device Manager appears, click on View > Show Hidden Devices.
Unplug the G27 Racing Wheel.
Expand the category "Human Interface Device" and "Universal Serial Bus Controllers".
You will see sub-entries with lighter, transparent icons. These are called "ghosted devices". Select and delete all of those entries. Just do it one at a time.
Restart the computer
Plug back the G27 wheel into a direct USB 2.0 port.
Check if the wheel is properly recognized in 'Devices and Printers" and "Game Controllers Settings".
Physically the wheel seems ok but it's the drivers that appear not to work and after numerous attempts of un-installing / re-installing / rebooting I can't get them back to a working state.
In Windows Device Manager the G27 Racing Wheel shows up with a yellow ! (not configured correctly) under "other devices". If i try to update the drivers by 1) Searching automatically and 2) picking from a list of available drivers (e.g. the "USB Input Device" that came up as compatible) I just get the Windows Encountered a problem screen (attached below).
I can only think of 2 options 1) Rebuild Windows on my PC or 2) Buy another wheel (and not a Logitech!).
So any suggestions would be gratefully received. Thanks in advance.
