i've never had this problem in the past and is relatively new to me, i plugged in my usb device and it said that it malfunctioned, so i do the rationaly thing, reboot, but still doesnt work, i left it and unplugged it for over 30 mins, still the same, so i checked it on device manager and saw that it didnt have power, i tried leaving it plugged in while i reboot, then my computer started making a beeping sound and wouldnt continue to boot unless i unplug the device, like i said this never happened to me before, so i tried plugging different kinds of device and found out the problem only occurs to usb 2.0 devices, usb 1.0 devices (keyboard, mouse) worked fine, the things is i've been plugging and unplugging usb 2.0 devices on my computer for the past 5 years and nothing bad happens, then this ramdomly occur, i wonder if it's a hardware problem or a software problem, hope someone can help me out. thanks
