I have an HP Pavillion running Vista Home Premium 32-bit operating system and AMD Turion Mobile Tech 64X2. The notebook has 3 standard USB ports. I've been able to use these with any USB device with no problem until lately, just one of them won't recognise any device plugged into it. EXCEPT, if I plug in an external 4 port USB hub, it recognises that as well as any device plugged into that external port, BUT runs them only as a USB 1 (standard) rather than the USB 2 (enhanced). I looked under Device Manager. No warnings or errors are noted by any of the controllers or Hubs. I tried uninstalling all of the controllers and hubs, Vista reinstalled them, but the port still doesn't work right. Is this a hardware problem, or is there a software solution? HP reccomends doing a full system restore, but that seems a lot of hastle just to get one of my ports working right again. I did try plugging in an external hard drive to that port (before it went bad). I used a power adaper that was 12 V instead of 5V, for not more than 30 seconds. Could that have messed up the port? Any suggestions welcome. drjaxon :thumbsup:

Most definitely. Does the external hard drive continue to work?

This is yet to be determined. I couldn't get the ext drive to be recognised by my lap top (too little USB power - I guess), and it wasn't being recognised by an eMac. I need to set up my old Windows 98 desktop machine to see if it might work with that. Although the 98 machine has only one USB connection and its to the mother board.

My guess is that port is now dead. I did something similiar to
my desktop box after first building it and that one USB port has
never worked since. Shame too because it's on the front panel and
I use those a lot for USB joy stick and my PSP and phone hookups.
