The right way to Repair USB Not Recognized in

Laptop Brand and Model: Acer Aspire 3640
Problem: This laptop came in with the following complaint:
USB Not Recognized (one of the USB devices plugged into this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message).
Diagnosis, Cause and Remedy: Every time an USB is inserted into the web the following error would come out: Usb Not Recognized (one of the USB devices linked to this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message).
One cause in this problem is how the driver for the USB controller gets corrupted. The primary thing I did was updating the driver's seat for the USB controller. After updating the driver, the actual issue still exist. When the previous method, cannot solved the error, you need to repair or reinstall the Windows Operating System because sometimes the O. S. (Operating System) gets corrupted due to viruses or some some other reasons. When I finished repairing the U. S., I turned on the laptop once again and unluckily challenge didn't gone away from you. Thinking that the corrupted system cannot be restored by simply repairing the Operating System, the second step I did was that I reformatted this laptop hoping it can be restore. After reformatting the laptop and installing the respective drivers for the peripheral devices, still no luck, regrettably error was not eliminated.
I told myself 'this can't be' usually when you reformatted the Windows operating System, all will be going to back to normal, but in situation it did not only. I now suspect hardware problem on the laptop, So I made the decision to disassemble the laptop and free the motherboard from all dust, as what I've said in my previous articles, that the dust is also one factor will cause the motherboard electronic components to be shorted. Because when dust gets thick it will are a conductor.
After disassembling the laptop and taken out all the dust. I tested the voltage on the terminal of the USB port. The normal supply voltage for that USB port may become is working fine is 5v DC enough to switch on USB devices. The voltage is just normal after I tested it, Dilemma is a touch harder because I've already done several possible solutions which usually used to solve this kind of problem. After doing all the previous steps and still not fixed the problem, I stopped for awhile and further analyze what's really causes the problem.
Upon thinking, It came to my head that what should the flow of current on the USB port that is generated by the provision voltage is already deteriorated. For your information even if the particular supply voltage can be normal, say 5 volts DC, however the current (measured in amperes) is already deteriorated, still It cannot supply enough power in order to make it worse the USB devices work. The final method I've that can solve this problem was that We used an external USB hub 2.0 which inserted from among the list of laptop's USB plug-in. After installing the USB hub ii.0 and whenever I connect any USB devices, it already works perfectly fine and the USB Not Recognized problem was completely flushed out.
Hope this article helped you get some ideas about solving USB Not Recognized problem in Replacement windows.
