Question about Computers & Internet
I see according to the 7200's specification sheet at the Plustek website
that the 7200 is packaged with a 15V, 1.0A output power adapter.
You must be sure to connect this to the device for it to receive its required amount of power to operate its moving parts, which the USB power output of 5V, 100mA will not provide.
If the power adapter is connected to the device and you still get the same message, you'll have to test the power adapter to ensure it is still giving the correct output.
This can be done with a multimeter. If you're not sure how to use a multimeter to perform the test, I suggest you take the power adapter to a PC repair shop or electrical repair shop where a technician can test it for you.
Hope this info helps you to solve your 7200's power problem.

USB ports operate in pairs from a usb host controller. Normally these pairs of ports are side by side (ie parallel to one another along their longest side) each pair of ports can onlhy be supplied with a limited amount of current.
You can try either plugging the scanner into a port that has nothing in its adjacent pair OR
You can buy a powered USB hub that will be able to sustain the current required for your scanner

Tips for a great answer:
Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive power and data cables IDE SATA
the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty
computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error
even something as small as a faulty electrical or fan lead can cause you problems
motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail
check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working
also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in
check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat
Thermal compound is a sticky paste that is placed directly onto the CPU.
Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.
hope this helps
