I have an ASUS M2N-E motherboard, which is about two years old now. Over the course of its life, the USB ports have one by one stopped supporting USB 2.0 and will only recognize devices as USB 1.1, usually after the power would flicker, causing the PC to shut off (I think this was the cause of a few). Recently The last port, of four, randomly stopped supporting USB 2.0. I have reinstalled Windows to see if that was the issue, which made no difference. Also looking through the BIOS I could see no options that would be related to the issue. Might anyone have any ideas as to how I can troubleshoot this issue, or fix it. Or should I just buy a PIC USB card? Thanks
My Windows install comes with SP2 which provides USB 2.0 support for my motherboard. I didn't install the other motherboard drivers, since I've never had to in the past.
Windows also comes with driver support for your graphics card but at the end of the day you wouldn't want to play games using it. Same goes for any other device connected to your PC.
It can't be the drivers, since they have worked fine in the past (I reinstall windows regularly). The purpose of the reinstall was to see if there was some other program, or even bad drivers, affecting USB 2.0.
It could be the mobo i guess going out. If you can't buy a new motherboard now, try getting a PCI USB2.0 board. Those are really cheap.
I had the same problem, my USB ports are 2.0 but they were reading 1.1 even after installing drivers plus SP2. So all i did was went in to my devices and updated my USB to 2.0 using the motherboard disk, this was the only way i could do it.
