In my PC USB ports are not detecting any mouse. If I put any pen drive it is detecting. I repaired my win-xp sp2 OS. I re installed all drivers. But problem was not solved.What shoud I do now?

Unplug all your usb devices. Go to device manager, then >USB controllers and delete all the controllers in there, it will not delete some, just delete all the ones it will allow you to. then reboot the system. Plug in each usb device one at a time and it should find each one.

Icannot download anything in my pc like songs like movie

Do you mean from web sites?
Or do you mean from a handheld device such as an I-POD?

Web downloading may be limited to how good your internet connection is. EG DSL; CABLE; DIAL-UP
If this is a problem how do pages like load up?

If the issues are potable devices aka I-POD then most likly the USB port in the pc is not functioning
The presario dates back to win2000 / w98 days were drivers for the usb ports were never installed by the pc manufacturer. The harware may be there ports ect but do not work. Win
xp started the true intigration of usb hardware when installed. You did not mention what operating platform ur using so im speculating here...

Usb port is not working in 1131 tx running on xp

You probably need to get the right drivers for XP.Even though XP may seem to have installed all or most of your devices you still should get the correct drivers starting with the chipset driver.Make sure you install the chipset driver first,then all the other drivers put out by the manufacturer.Go to their website and in support and drivers get ALL of the avaliable drivers for XP and update your drivers,especially the chipset.

USB DVD ROM no detected

You need XP service pack 2 or later installed on your notebook. Does your notebook detect other USB drvices, if not your USB port on the PC is gone. If the USB prt is working and you have XP service pack 2 installed then you probably got a bum DVD drive so return it and get another.
