Guys, i'm having a problem with my USB ports on a system i just assembled. Let me start from the beginning, i'm currently using an old USB laser laptop mouse (i'm still waiting for my new keyboard and mouse to arrive) for which i have no software cause its so old, when i first booted up the system it didn't work at all so i had to use a ps/2 mouse instead. Upon second boot i entered BIOS to see if USB devices are enabled and they were, after that it started working. I have 6 usb ports on my system, 4 in the back that come with the mobo and 2 case ports in front. It worked for a while and was plugged in the mobo, then all of a sudden i get a message in windows that the USB port has malfunctioned and the mouse stopped working. So i plug it into a different port and it works. When i booted the system today the mouse wasnt working again, so i had to try 2 different ports before it worked. After that i decided to test all of the ports, most of the times they work but sometimes they don't. I don't understand what is going on here, is it a common problem with new systems? Could it be that this is a software problem, may be i should wait till i get a new mouse that comes with a cd and install it? May be i need USB 2.0 drvers, is there such a thing? P.S. What do i do about the malfuntioned USB port, is it dead?
