As to what may be causing this laptop USB problem, this may vary depending on the brand and model of the laptop. With some systems for instance, the laptop USB problem wherein the ports work normally when devices are plugged in but an error message pops up when the device is unplugged, the most common cause is an issue with the USB driver.

The drivers may be downloaded by using the utility software that comes with your laptop. Doing this may be enough to solve issues with the USB controller as well. If installing the latest drivers doesn’t work, the problem may be caused by your operating system.

Some users also seem to have traced this particular laptop USB problem to a bluetooth emulator. In such cases, the error message pops up at the same time as the emulator.
