Locate the USB receiver for the device, and then make sure it is connected directly into a USB port on the computer.
A USB hub might not provide enough power for your device to connect properly.
If you cannot locate the receiver, check the original packaging. Some HP Touch and All-in-Ones come with the USB receiver preinstalled in the computer. Or, look for a USB storage container on the device.
Look for and remove any battery tabs from the device. This tab prevents the device from receiving power.
Make sure the device has adequate power.
If the device uses batteries, install new batteries according to the guide in the battery compartment.
If the device is rechargeable, connect the charging cable to the device, and then to a power source, such as a USB-charging port on the computer or an external USB power adapter.
