It may very well be drawing too much power from your laptop. These are fairly intolerant of devices that draw higher current like printers and some hard drives. You may need to get a small USB Self-powered hub. These are USB hub/splitters that have their own power supplies. These usually provide and tolerate higher power draw. To test, if you can connect the same printer to a desktop, you will likely see it works fine.

INSUFFICIENT POWER - USB PORT
If you get an error message "Insufficient power to operate USB device" when you plug a USB device into the computer's USB port or the un-powered USB hub that is attached to the computer's USB port, then this device is drawing excessive current that the USB port cannot supply. The maximum output from an USB port is 500mA. In case such as this, you need to purchased a powered USB hub and connect this hub into the computer's USB port and then connect the USB device into this powered USB hub.

The chances are that the portable drive is drawing more current fom the USB port then the port can supply. The current limitations on the USB ports are controlled electronically and if anything is connectedthat attempts to draw more power then the port can safely supply, the port is shut down.
You may have to use a USB power injector which you plug into the laptop and then plug the drive into that.

Usb ports not recognized


Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

USB Problem


USB devices are allowed to pull up to 400mA for each port. Unfortunately if you have a keyboard with the handy USB ports on it and you plug in your memory stick, you still are left with 400mA for your keyboard AND USB stick COMBINED. The keyboard will draw it's power from the USB port on the computer, so unless you have a device that has it's own power source, each port on your computer can draw no more than 400mA.

My averatec series 3200 notebook cant detect my usb device


The flash disk could be faulty, especially when it draws too much power, and this will cause the USB ports to shut down and the other USB devices won't work until the faulty device is removed.

Usb ports


  • The driver for the device is faulty. When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver. If the computer prompts you for a device driver, check the information that came with the device or go to the manufacturer's website to see if a driver is available.
  • The USB port might be defective. If the USB device is connected to a defective port, the device will not work. Try plugging the device into a different port. If all the USB ports are being used, unplug a device that you know works, and then plug the problem device into the port that device was using.
    If the device is plugged into a secondary USB hub with other USB devices, unplug the device from the hub, and then plug the device directly into a port on your computer.
  • Other USB devices might be drawing too much power from the hub. The device you are trying to use might require all the available power or bandwidth that your computer can provide. If other USB devices are connected to the computer and are drawing power from it, the first device might not work. If any other devices are drawing power from the hub, try disconnecting them, and then see if your device works. If this solves the problem, you might want to obtain a USB hub with its own power supply so that you have adequate power for all devices.

    Usb ports do not active


    One of the great features of USB devices is they can get power from the USB port. Plug in a thumb drive and it just works. The power for operating the thumb drive comes from the USB port. This works for small devices like a thumb drive but not something big like a scanner. The scanner need its own power supply.

    There could be several explinations for what you are seeing. Could be you are plugging in a device which is sucking too much power and the laptop is shutting it down. I would test the port with something small like a thumb drive and see if it works. If the thumb drive works but the other device does not a couple of things could be going on. Maybe the device just need power - is there a way to plug in a power supply? Or maybe the device is broken and shorted out. Does the device work on another computer?

    If something like a thumb drive does not work then it is a problem with the motherboard. Could be the USB ports are bad. It happens and there usually is no easy fix short or replacing the motherboard ($$$). Occasionally there is a BIOS setting for the USB ports. A bit of a long shot but worth a look.

    A possible work around would be to get a power USB hub. A hub plugs into a USB port and provides 4 or 7 USB ports. Good ones come with a power supply. When the hub is plugged into the power supply it does not draw power from the computer. Might solve your problem.

    Good luck!

    Qx5 microscope is shutting down.


    Does this device run from USB power.. (no plug in power supply) if so, the problem may just be that this device (not limited to microscopes) is trying to draw too much power, as not all USB ports are born equal (a common problem in laptops). the solution is to either buy a power supply for the microscope or get a "powered" USB hub (a usb hub with it's own plug top power supply) I hope this helps
