I've been through a very singular problem for the last few days.
My Windows 7 suddenly become slow to make USB Mass storage devices ready to access, but this happens only the first time I connect them on my computer.
If I start the computer and connect the USB Mass storage device (that was recognized a long time ago) it takes almost 1 minute to be ready for use... After that, every USB Mass storage device that I connect to the computer opens almost instantly.
If I restart the computer, the same thing happens.
I've tried to reinstall drivers
, to disable security, looked for a service that controls it, verified the power options and verified every hardware...
Where is the problem? Can somebody help me?
