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:

1. Disconnect the power supply, USB Host cable, and all devices from the USB Hub.
2. Leave the USB Hub disconnected for 30-60 seconds.
3. Reconnect the USB Hub’s power first.
4. Connect the USB into the host, then plug USB devices back into the hub.

If this issue persists, if possible we have a tool that automates collecting a set of log files from your system. You can download the PlugDebug tool and learn how to use it by clicking on this link:

Ensure that you have the USB Hub connected to the computer when the PlugDebug application is run. Then send us a copy of the log files to Support@Plugable.com
