the thing is no any usb devices are working it says usb not recognized. But I don't know why external hard drives work. When I went to device manager there was yellow exclamation sign saying unknown usb device. then I uninstalled all usb drivers and restart then connect the usb there was yellow exclamation mark on usb mass storage device error code 10. then when I replugged the device it was same again as before saying usb not recognized.
