PC hardware: USB device not recognised
USB device not recognised

HP DV6108 - running XP
When I plug my external hard drive into the USB port up I get this error.
"USB device not recognized
One of the USB devices attached to this computer has malfunctioned and windows does not recognize it, for assistance in solving this problem, click this message"
When I click on that message it pulls up a list of USB ports
USB Root Hub

I only have three USB ports on the laptop. The external hard drive works fine if I plug it into either port on the left side of the machine. The port will work fine for a wired optical mouse and I just tried my IPOD and it worked. I use this port also for checking coeds one my car with an OBDII to USB connector, and that doesn't work(and can only work with that COM port). I only got this external a month or so ago and think that it might have screwed something up. I tried to do a restore, but that didn't change anything.
When I go into the Device manager it lists these under the USB
Universal serial Bus Controler
Intel® 8280G (ICH7 Family) USB universal Hose Controler 27C8
Intel® 8280G (ICH7 Family) USB universal Hose Controler 27C9

Intel® 8280G (ICH7 Family) USB2 universal Hose Controler 27CC

Again, I only have three USB Ports.
HELP me get this back up and running.
Thanks

I see the dv6108ea came with XP.
If you want to try one driver, it's the ICH7 item at http://h10025.www1.hp.com/ewfrf/wc/softwareList?os=228&lc=en&dlc=en&cc=us&product=3308773&lang=en
I have this issue with my Palm TX PDA. It's not a fault of the laptop and I know to get around it. Since this chipset has that many USB controllers wouldn't it be fine to report all of them?
-> But reading your post a second time it sounds as if this drive draws power from the USB port. If so, the only fix is to have an engineer beef up the power to the ports that don't work.

DV6108nr Didn't realize there where other 6108's
It's a 1 TB external that has it's own power.
Will try that driver and update
Let's hope its not this model.

I read the post you linked to, but It's just one USB port that doesn't work the other two work fine. The brand of my drive is Cavalry.
Then try the old fix.

Place an USB 2.0 HUB inbetween the non working port and the drive.
If this works then it's the old USB issues that have come back to haunt you. I don't want to type in what they proves but the choices are:
1. Use a drive that works in that port.
2. Use the USB 2.0 Hub.
3. Replace the motherboard.

warranty

I have a warranty from best buy on this laptop, should I bring it in to them and have them diagnosis the issue, if it's hardware then they will replace what's bad, of course I'll have to backup everything first, since this is the wife's laptop
I don't have a USB hub right now, but I will go pick one up.
Or...

It's only USB 1.x on the port that didn't work. Not unheard of and I leave it to you to research that. I did the research on why so many ports being reported.

Why not go with what works where it works?

In reply to: warranty by AKIELB
I think you wrote it works in the left ports. Why not go with what works?
reason why
by AKIELB - 12/31/08 2:36 PM In reply to: Why not go with what works where it works? by R. Proffitt
The reason why I need that port, is my Car code reader uses Com4 only and that port is set up as com4. Also, I like it when everything works the way that it should.
Thanks for your help, I'll get the USB hub tonight and give that a try.
It worked - so that's a bad thing?
by AKIELB - 12/31/08 9:04 PM In reply to: Then try the old fix. by R. Proffitt
ok - I purchased a CyberPower 4 Port USB hub. That worked. I connect to the port via the USB hub and it reads the drive. What does this mean, it's for sure a Motherboard issue?
something else. I was looking in the device manager and realized that I was missing the "PORTS (COM & LPT)". Searched around and figured out how to get them back. New problem, I need was using COM4 before to connect to my car - now that says "in use" when I try to reassign the COM#. What would cause this? What is using the COM's? Is there a way to find out?
Sorry for all the questions. Thanks
Just a link.

http://www.patentstorm.us/patents/6993102/description.html is fairly technical but gives you a peek under the USB hood. The test is what it is and only reveals there is an issue with the USB clock and/or jitter. There is nothing that we do besides leave the usb hub there or replace the board that holds the not so great USB port. In the case of laptops this runs 300 to more dollars.
You can see why I just leave USB hubs installed.
My USB to Serial adapter does that same thing. It's in the documentation how to press onwards and make the change anyway. One owner was hopeless and refused to click the OK button to change it anyway in spite of the demo where I showed it was OK.
