Hello All!

I have a Compaq nx6110 notebook that has given me 6 years of reliable service until recently. I started getting messages periodically that said a USB device had ceased to work. I would unplug the device and then plug it back in and it would work fine. The problems became more frequent with both USB ports. Now, every time I plug in a device (or even the cable) to the USB port, my system locks up completely. I was able to reset the CMOS a few times by pulling the battery, and the problem would go away. Now it happens every time. I've exhausted the usual routes of diagnosis and am now flummoxed.

Is this a driver issue? Are my USB ports failing, shorting? Is the motherboard failing? Should I face the music and make this a parts notebook?

Fortunately, I'm a compulsive back-upper so the data is safe.

Thanks in advance for any advice!!

Hi Nunbet1037 and welcome to BC.com

You did not post what operating system you have, but if you go to Control Panel and Device Manager and look for Universal Serial Controllers and check the status of their properties, by right clicking them.

Post back what you see there.

Hello MrBruce:

Yes, I suppose the OS is important. Sorry about that. I'm running Windows XP SP3.

There are 2 USB ports on this notebook. I have used it with a 4-port USB Hub when travelling and a 7-port Hub when at my office. Here's the data from the Device Manager:

Intel® 82801FB/FBM USB Univ. Host Controller 2658 - Working properly, no conflicts, PCI Bus 0, Device 29, Function 0
Intel® 82801FB/FBM USB Univ. Host Controller 2659 - Working properly, no conflicts, PCI Bus 0, Device 29, Function 1
Intel® 82801FB/FBM USB Univ. Host Controller 265A - Working properly, no conflicts, PCI Bus 0, Device 29, Function 2
Intel® 82801FB/FBM USB Univ. Host Controller 265B - Working properly, no conflicts, PCI Bus 0, Device 29, Function 3
Intel® 82801FB/FBM USB Univ. Host Controller 265C - Working properly, no conflicts, PCI Bus 0, Device 29, Function 7

USB Root Hub - Working properly
USB Root Hub - Working properly
USB Root Hub - Working properly
USB Root Hub - Working properly
USB Root Hub - Working properly

All of the drivers are current as I recently removed the devices and allowed them to be re-installed through PNP on a cold boot after pulling the battery and power.

Thanks for your help!

Rich
