USB Ports Failure

Compaq preserio (hp) / 5000

Specs: Windows Vista

I have 6 m/board connected USB slots which are all dead. Device Manager shows 5 controllers/6hubs. Even simply devices such as a mouse, Windows does not recognize. The properties of ec.controller say they are working properly as do the hubs. System info shows no conflicts in IRQ or in/out. All my drivers are up to date. I have reset the Reg. and also cleaned it using Reg. Cure: My problem will not allow me to connect my new Kodak printer. I am at a loss and do not wish to do a recovery and louse a lot of work restoring my computer to its original state. Back up did not work. Two brains are better than one--especially mine. If anyone can help I will really appreciate it. Thanks

How old is that PC?

Did you have any AC/Power issues or surges?

Try this 1st:

If that doesn't work, try booting into Windows Safe Mode to see if USB works. If it doesn't, chances are it is dead.

It is about 2 years old and the OS is Vista. I tried the two suggestions you made. All of my controllers are powered up with an allogation of 500 mA per connection.
'Actually, the ports are not completely dead but they might as well be since they are useless.

What happens is that Windows does not recognize any device pluged into one of the USB slots. Occasionally, I get the message that the drivers are loaded for this device, but when I look at the properties of that hub, it says no drivers are loaded for this device. Also, it list the connection as an (Unknown device) and Windows does not recognize it.

The problem may be with Windows itself rather than the controllers or USB Hubs. It is beyond my expertise.

PC Doctor is not on my computer. I looked at it and it was designed for XP whereas I have Vista Basic. Thanks anyhow.

The next step per that HP article is to test your USB ports with PC -Doctor:

I don't have PC Doctor on my computer. However, I am going to look it over closely. I have had programs designed for XP that did work on Vista.

You can use the PC-Doctor Offline version here:

PC Doctor would not run on Vista for me. Microsoft has a similar program called Microsoft Fixit, but it is as usless as the tits on a bore hog. It barely skims the surface for problems of this magnatude.

As a matter of fact, I find that others with the same problem are blaming it on an update #KB938371, but I do not see Microsoft admitting to it or coming up with a fix for it. It cannot be deleted from my computer. Whatever is causing it is a disaster to a lot of computers or persons owning computers using USB ports. I bought a Cannon first and it quit after two weeks so I took it back to Wal-Mart and got another one. It didn't work either, so I then bought a Kodak and still have the same problem, so I am 99% certain that the printers are not at fault. When I checked the update, it was installed at about the same time my original printer stopped working--so what can I say, what can I do? .

BORE hog? Ha ha…sorry for not clarifying, but you would need to run that PC Doctor Offline Diags setup on your spare XP PC (we all have spares right? ;-) to set up a bootable CD or Floppy. Then you would boot to that CD/Floppy and run the diagnostics. Always check the hardware first before messing with the ~50 million or so lines of code in Vista (God I hate Vista).

Q: When was that Update applied? KB938371 is rather old, came out on 4/7/2008

Let's go back to your 1st Post William

Q: When did all of your USB issues start happening?

Q: What Version of Vista do you have and what Service Pack Level?

- I've actually had good results from the MSFixit Programs; they can be very specific per your problem however and you need to know which MSFixIts to run. Did you run one; and if so, which one?

Is the Windows installation the OEM version from HP? If not, you may need to install chip set drivers.
