I would suggest you bypass the troublesome circuit and the overload of curent density by powering down the unit before charging. Wait a moment before re-starting the unit. In your personal settings you may fine an option of when to turn off, it may be set to never. The driver on the unit is in question as it seems to need the one on your computer to function. See if you can download a new version other than the one currently on your unit, or maybe the one you have is somehow currupted, then try the same one but from a different source than where you originally aquired yours. You will need to turn off your firewall and other security in order to download the driver, once you are at the trusted site or your internet settings can interfere; another way is to list the trusted sites in your internet options pages, which will allow the downlaods to be uncorrupted. Hope this helps. GOD bless MY Love, Walneta
