Is it possible for usb ports to work with some devices and not others?

I have a usb device, it works on 2 computers i have tested it on. One computer it doesnt work on. Would this be driver related? or what else could cause this?

Two of them you just plug it in and it automatically installs. the other it doesnt install. almost nothing happens.

the same usb ports will work with other devices in that port. i have tried it in many ports on the same pc and no joy.

Its a usb pen/mp3 working on other pcs no problem, so def not the pen. I believe its either a hardware or driver error. there are no drivers online for this item. i have searched and cant find any.

Uninstall everything under usb in device manager and reboot,let xp install its generic drivers.
Try the pen drive again.

absolutely everything?

I have various ones:

Intel(R) 82801g (ICH7 Family)USB universal host controller - 27C8
many USB root Hubs.

Is it safe just to uninstall them? are these just created when a usb device is plugged in and are they easily replaced?

They are re-created when you re-boot your PC as per skidzy's suggestion.

Yes everything,you are about to refresh all usb ports.

Alternatively,keep device manager open and plug in the usb pen drive.

This should change your screen and show as MASS STORAGE DEVICE.

Then try to uninstall just that.

Ok, its actually on my friends pc. I will go round in the next day or two and try that. Do you have any more suggestions that I can go armed with? I really want to get it done in one more visit!

I have searched for drivers for the mp3 player with no joy!

it just seems to show as usb root hubs.

could it be driver related? as in if i look up the driver on a pc it is working on and then paste it onto the computer it isnt, could that do the trick?

ok, i will try these things and hope that they work.

How confident are you that this will cure the problem? I know that mp3 players can be somewhat problematic.

Any other quick fixes incase these dont do the trick?

thanks for all the responses so far, really appreciate it!
