xp mce usb periphials fail to load

[imchar]

i think i changed the settings on the pc so that whatever is needed to load a periphial via a usb connection will not load.

the only hardware that is recognized via my usb ports are devices previously installed successfully.

the pc no longer will recognize/install external hard drives

it won't recognize or install my 60 gb maxtor or 2 different 3.5 inch floppy drives, one or which is memorex the other smartdisk.

when i plug them in the pc shuts down, restarts and then shuts down and reloads over and over untill i unplug the usb cord.

i'm running

Some times devices are associated with only one port as mention in the last hypertext link listed below. It may be USB auto powering off the reader or not powering it enough. I don't know your mobo but see if there is another USB header that you can plug the reader into. Then try unchecking the "Allow the computer" under Power Management tab for the relevant hub. Whats happening is unique serial numbers are not included by a manufacturer. And placing it into another port can confuse Windows Xp.

i've tried using different usb ports, same problem

I would suggest you to install drivers for your external hard drive and at the same time try to check out on another computer if it's working fine then there is some issue with your computer and at the same time check out below links for more solution

sorry, not enough info for me to finish following the directions.

i found the "allow the computer" and deselected it.
that option is only available for the usb 4 port hub i added to the computer, not the usb port factory equipped.

now when i use the 4 port hub windows does not shut down, but it also does not recognize the floppy at all.

the factory equipped hub detects it but windows shuts down before i can "read" from it.
