I am having major problems and at the end of my rope, can somebody please help...left Powered USB device connected to my PC for 1 hour when I came back the pc was off and when I rebooted USB ports (8) didnt work...
From Fruit bat: "Refresh USB Ports In device manager Uninstall EVERYTHING under the heading USB, reboot the PC let XP find and install new hardware. Your equipment should now be recognised.
If no good then check USB is still enabled in BIOS.
If still no good then you may have blown the non replaceable fuse on the motherboard."
...I tried this and still nothing...I have been to various forums and they all say similar things, except for one point. One of my devices, a graphics tablet seems to still draw power but remains undetected, I say this because its little LED flashes as normal. So if it is drawing power I can't believe that non replaceable fuse has blown. Also when I plug in a usb gamepad its little LED flashes once and then goes off.
I also looked up about my mother board which is by all accounts very reliable ASUS P4800 Deluxe.
This is a very big problem for me as I have many devices that run off usb for music production, as i am a working musician, I am sure you can understand that this is threatening my livelyhood. Please help.
You could try booting from a Linux live cd to see if any usb devices work, if they do then you know its a windows problem, in that case use system restore. Press F8 at start up and select "last known working configuration that worked"
