USB Ports On Mother Board Not Working
Hey Guys,
I guess there is too much text in this post but I wanted to give you all a clear description of my problem please help. I have attached few screen shots as well.
I have some problems with my USB ports. I have 2 ports in front and 4 at the back (on the mother board). All these ports were working fine, since last 2-3 weeks there seems to be some problem with it.
I have a webcam that I connect via the back USB port, I never disconnect it. Recently the power supply unit failed when I tried to start the pc. So I replaced it with a new one, everything was back to normal.
Then after a few days or a week I opened my pc because it one of the front USB ports was not detecting my flash drive, while doing this I disconnected all the wires from the back of the CPU including the webcam.
When I restarted the pc the back USB ports stopped detecting any devices, there was a pop up stating, "One of the USB devices attached to this computer has malfunctioned and Windows does not recognize it"
So I tried connecting it in the front port, there came a pop up stating, "Your USB Mass Storage Device can perform faster if it is plugged into a hi-speed port"
I never use to get a message like this in the past and another thing I noticed was that the transfer speed has also reduced drastically. I was copying a few movies to my friend’s flash drive and it took ages,
Transferring at a speed of 800-900 kb/second. The transfer speed was pretty fast on XP and on the same port, I always use the front ports. This is the first time I tried to transfer file on Win 7, my friend using Win 7 gets speed around 30-50mb/sec.
I have the latest windows updates installed, I have checked for driver updates on Intel site and I already have the latest drivers. I have reinstalled all USB ports from device manager.
I don't know if this is a software or a hardware issue.
Please guys help me, I can't find a solution anywhere.
Thanks,
Chinu
