I know this is an old thread, but I experienced similar issues when configuring on Windows 98SE, but after a lot of trial and error managed to find a solution and now have my Stinger fully operational.
Some steps below which hopefully may help OP if still having issues and anyone else who may stumble upon this post experiencing the same problems.
1)Install Gravis Experience 3 which comes with the device. Reboot when done.
2) Connect the Gravis Stinger to the machine, and let it find and install the driver automatically. Reboot. (Note, this brought me to same problem OP had).
3) Remove the Gravis Stinger from Device Manager, disconnect it from the serial port, then uninstall Gravis Experience 3. Reboot.
4) Locate and download Gravis Experience 4.5. Install, then reboot.
5) Connect the Gravis Stinger back to the machine. If not detected, just refresh in Device Manager and it should install. Note - again this still isn’t going to work, but we do have SW installed now which will eventually work. Reboot, again!
6) Confirm you see “Gravis Stinger” under Sound & Game devices in Device Manager, working ok with no conflicts (it may show GRAVIS SERIAL PAD - so long as it’s operating ok according to Device Manager we can continue).
7) Update the driver > Display a list > and Show All Hardware. Head to [Standard game device] and select HID-compliant game controller. Ignore any driver warnings and select to allow installation. Let it complete, then… Reboot.
😎 Double check Device Manager to make sure you still see a device there without conflicts.
9) Head to the Control Panel > Gaming Options > Add > Gravis Stinger. This should now work and add the Gravis Stinger and show a status of OK.
You should be good to go now, and Gravis Experience should also work. A bit messy, but worked for me on my Win98SE install on an Inspiron 8100?
Hope it helps!
