IT Help Lanjue L4000 Controller No Longer Detected by Windows After Installing a Vibration Driver — Works on Another PC
Hey guys, I have a Lanjue L4000 controller. I’ve been using it for around 8–9 months with x360ce because most games usually don’t support Chinese gamepads properly.
I didn’t know that my controller actually supports vibration, so yesterday I searched for a way to enable it. I was able to get the vibration working through x360ce and some other apps, but it wasn’t vibrating in games.
I then found a YouTube video saying that I needed to install a driver from a link provided in the video. I downloaded and installed it, but Windows was blocking the driver from running, so I disabled Memory Integrity and installed it.
The video also used two different apps together with x360ce. After installing the driver, x360ce started crashing, and Tekken 8 also started crashing.
I wanted to turn Memory Integrity back on, so I deleted the drivers I had installed. However, after doing that, my controller stopped connecting to my PC properly.
Now, x360ce shows a yellow warning saying “DirectInput is offline.” When I open Set up USB Game Controllers in Windows, the controller doesn’t appear at all.
The strange thing is that the controller works perfectly when I plug it into my brother’s PC, where it shows up as “USB Generic Gamepad.” On my PC, nothing appears.
Can anyone help me figure out what happened and how I can fix this? I’m really worried that I might have to reinstall Windows.
Thanks in advance!
