One of my laptop(dell vostro 2421)'s usb port, i usually use for plugging usb modem, and sometimes usb flash. But one day, when i plug usb flash, it won't recognise. I plug mouse, also not recognise. But when i try to plug modem, it actually works. so Why it only work with modem but not other usb device.

I went to device manager and check for driver update, but say the driver is up to date. :(
