Malfunctioning USB port

[tomu]

Hello,

This fault has just developed after two years of proper functioning.

USB ports on my Toshiba laptop (Vista) recognise all devices except my Nikon S3000 camera. Camera IS recognised by other computers. Same cable throughout.

I've cleared the USB root hubs.

Welcome to Tom's Hardware Forums!

You have properly identified the issue. USB (ans SATA) have a limited life as far as plug/unplug is concerned. In this particular case, the contact pressure is inadequate. A new cable might solve the issue.

On my Nikon DSLR, I do not unplug the USB cable. This is a little inconvenient, but works well.

I got over the problem by doing a complete virus/malware check and then reinstalling the Nikon S3000 driver via the Device Manager. No idea why it got corrupted in the first place, but obviously something untoward happened. I didn't think it was a cable/connection fault as the cable worked elsewhere and my spare cable didn't solve the problem. Thanks anyway.

That's good news! Now do a complete system backup on to an external drive. I believe in regular avti-virus scans, and regular backups!
