Cycle the power to a device when it disconnects from a PC

The power cycle on disconnect feature cycles the power to each USB device when it disconnects from a PC. The power is turned off for 1 second and then turned on. This is useful for security devices that may refuse to reconnect to a PC without a power cycle, virtual machines that reboot, and devices left in an unexpected state.

This feature is globally enabled by default on the Hub. You can choose to globally disable it.

Note This feature is disabled by default on the AnywhereUSB Plus 24 variant without Wi-Fi. If your device has a serial number greater than or equal to AW24-010000, this feature can be enabled. Otherwise, the feature does not work as expected and should not be enabled.

When a disconnect occurs, the Hub turns off power to the device and then one second later turns it back on. The re-powered device is then ready to make a new connection to the same or a different PC. Note that if the PC is connected to the group, the USB device can only reconnect to that same PC.

Disconnects happen when:

• A device is manually disconnected from the PC.

• From the AnywhereUSB Manager, expand a Hub to display the groups connected to the PC. Right-click on a device in a group and select Disconnect Device to disconnect the device from the PC. This menu option is not available if a PC is not connected to the group. The power to the device is cycled and the device reconnects to the same PC.

• A group of devices is disconnected from the Hub

  From the AnywhereUSB Manager, expand a Hub to display the groups. Right-click on a group and select Disconnect from Group. The power to all of the USB devices in the group is cycled and the group waits to be connected to the same or a different PC.

• PC and/or the Hub reboots

  If the PC and/or the Hub reboots, then after the keepalive timeout occurs, all of the USB devices that were connected to that PC are power cycled.

• PC and/or the Hub loses connection to the network

  If the PC and the Hub lose network connectivity, then the USB devices that were connected to that Hub are power cycled if the connectivity is not restored before the keepalive timeout occurs. The groups are then ready to connect to the same or a different PC.

Considerations

The following examples explain situations in which this feature does not work as expected.

• If you have self-powered USB devices, then this feature will not be able to power cycle this device. An example is a hard drive with a power cord plugged into a power source other than the Hub.

• If you have devices connected on a downstream USB hub and the hub does not support USB power control, then the feature will not cycle those devices.

Note Additional power cycle methods are available. See Power cycle feature.
