If your USB Hub is having issues with some USB ports not connecting to the host computer, there are a few steps that you should try to resolve this issue.
Full power cycle reset:
- Disconnect the power supply, USB Host cable, and all devices from the USB Hub.
- Leave the USB Hub disconnected for 30-60 seconds.
- Reconnect the USB Hub’s power first.
- Connect the USB into the host, then plug USB devices back into the hub.
