disc drive MP3 player not recognised

[Ian]

My PC is about 5 years old and my MP is not recognised in my computer. It
works on my mother's newer PC. It shows up in device manager with a
question mark and won't accept the drivers (it shouldn't need them anyway)

I have an external hard drive and was wondering if that meant I had maxed
out.

The MP3 player is a USB device and my other devices are working fine through
all the USB ports apart from this one.

Hope you can help

Why do you say drivers should not be needed? What OS are you using? If not
XP are your drivers backward compatible?

I use XP. The MP3 player should simply show up in "my computer" as a disk
drive as it does in my mother's pc as already explained. This is a common
problem if you do a Google but there doesn't appear to be a common
solution....do you have one - a solution that is?

Have you tried other USB ports? Some have voltage others do not.
