If the unit has mains power, check that it is getting it. Also if it comes with two usb plugs then make sure both are plugged into usb ports on your pc. Try the unit on someone elses pc/laptop. if it works on theirs then your pc has a problem with the usb ports.

have you tried to plug it into another usb por to see if you get the same result, the original port might be in a locked state and may have had problems releasing the usb key.

USB device unknown


Make sure you are connecting directly to the computer's USB port, not through a hub. Try disconnecting other USB devices before plugging in the camera. Check the manufacturer's website for updaded drivers: if all else fails, a reinstall of the camera's drivers may be in order.
