There's really nothing to fix here.
I have a 32" Se32d850t Samsung computer monitor. For two months the USB hub worked fine. Now, it works intermittently or not at all to detect devices attached through it. However, it does work as a power source (for my phone)--it just doesn't recognize anything attached to it as a device. I have actually tested the USB ports on the PC it's connected to. All ports work fine on the PC. When I check USB Devices in Device manager, I don't see any warning or malfunction symbols. I'm running windows pro 10 on an HP really fast desktop with 16 GB ram.
