Usb device not recognized when I plug phone into laptop, it always worked before
in device management uninstall all USB drivers. restart the laptop.
if it still dont work then unistall the software for the mobile. restart the laptop
install the software again, then connect the mobile.
if still not working try your mobile on another pc or laptop, if it work then you may have a problem
with your windows USB drivers, which mean you will need to reinstall windows on your lap.
you can test you mobile with another usb cable also on your lap.
good luck
