# What to Do In Case of CodeMeter USB Bus Failure

## Scope

It is very unlikely for a CodeMeter dongle to die in the field. We have not seen one die across hundreds of installs and many products. Furthermore, if unplugging/plugging the dongle back into the machine allows licenses to be seen, we can remove a broken dongle as a variable. If the dongle were faulty, it would not appear in CodeMeter Control Center when plugged in, and licenses would not be available at any time.

This is most likely a power allocation issue of the USB *bus* of the machine on location (It could be a setting, the power supply, or the USB *bus* itself), but let’s start by configuring the CodeMeter Service to restart under negative circumstances.

## Requirements, Steps, Etc.

1. Go: **C**:\**ProgramData**\**Microsoft**\**Windows**\**Start Menu**\**Programs**\**Administrative Tools** and launch **Services**.
2. Locate **CodeMeter Runtime Server**, and right-click to select **Properties** in the appearing menu.
3. Under the **Recovery** tab, set the **First**, **Second** and **Subsequent failures** to **Restart the Service**.

Next, optimize your power options:

1. Go: **Control Panel** > **All Control Panel Items** > **Power Options**.
2. Tick the **High performance** option, and click Apply/Save.
3. Click **Change plan settings** for High performance.
4. Click **Change advanced power settings**.
5. Under **USB settings** > **USB selective suspend setting** set the option to **Disabled**.
6. Click Apply/Save.

Finally, Configure your Universal Serial Bus controllers.

1. Go: **Control Panel** > **All Control Panel Items** > **Device Manager**.
2. Next to **Universal Serial Bus controllers**, click on the **drop-down arrow** to reveal each surrogate Hub/Device.
3. For each entry, right-click to select **Properties** in the appearing menu.
4. Under the **Power Management** tab, un-tick **Allow the computer to turn off this device to save power** and click **OK** *(Note: Some of the entries may not have a Power Management tab. In this case, close the dialog, and move on to the next entry)*.
5. Restart your computer.

If the problem persists after observing these troubleshooting steps, we recommend sandboxing the configuration, and testing on another machine (there could be a problem with the internal power supply or universal serial bus of the machine on location).
