Guest mark Posted June 26, 2008 Posted June 26, 2008 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... -- Mark Roberts

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. -- Mark Roberts

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... -- Mark Roberts
Guest hrvgds Posted August 23, 2008 Posted August 23, 2008 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. Autumn
