usb not working.

[Guest mark]

About 3 weeks ago (may 2008) I found that one of our pc's had lost its

usb functionality. Xp pro, installed and running for 3 years.

It has a ps/2 keyboard, ms usb optical mouse and occasionally has 2

different types of samsung flash based mp3 players connected.

After much fiddling I declared the usb controller dead (pc was 8 years

old) and swapped monitor, keyboards, mouse etc to another box running xp

pro fresh install.

3 weeks later I have the very same problem on this box.

That particular box had run xp pro for 3 years without a hitch with a

gaming usb keyboard and gaming usb mouse and a usb external drive with

no problems.

 

The symptoms (identical on both boxes);

Mouse is found to be frozen at log on to xp.

Inspection of device manager shows following under

universal serial bus controllers:

 

standard enhance pci to usb host controller

standard openhcd usb host controller

 

both with a black exclamation mark on a yellow back ground

 

right clicking either brings up a code 41 error message.

 

I have tried countess attempts at uninstalling them, rebooting, scanning

for hardware changes.

Updating drivers results in a message saying the driver is fine.

 

Uninstalled sp3 back to sp2.

Checked bios for usb settings enabled

Changed bios setting to enable/disbale pnp OS.

Added a registery key 'usb' with a 'dword value of

DisableSelectiveSuspend set to '1'

Also looked in registery for key that has 'filters' (?) but it did not

appear to exist.

 

I am now baffled.

Please help...

No difference at all.

I take it you meant the .reg file on the right?

I guess I should add; that is ALL there is this section, nothing else

except these two items. No USB hub or anything and the PC has 10 ports

altogether.

 

I cant believe I have had 2 separate PC's do this and there isn’t a

solution.

It still doesn't work :(

I tried it twice; the second time after removing the 2 host controllers

 

I'm still baffled as to what happened to the root hub........

Well I fixed it by a full reinstall.

Repair did nothing.

Now its working fine.

I'm still baffled as to what caused the root hubs to disappear.

I have taken the precaution of unticking the 'allow xp to switch this

device off' box in the root hubs properties.

 

Thanks for listening...

Re: usb not working.

 

where exactly is the "allow xp to switch device off" option? I'd rather not

have to go through reinstalling parts of my dell laptop--I have enough

problems with it as it is.

Control panel>Device manager>usb controllers

 

right click each hub and choose properties and then choose power

management

 

Make sure that the little box labelled:

'allow the computer to turn off this device to save power'

is NOT checked.
