Yes, "cord off for 30 minutes" means leave the cord off/batteries out for 30 minutes. I've seen people complain that when they clear their CMOS it doesn't fix anything. They pull the battery/move the jumper, but don't unplug from the wall. See the wee LED's on the mobo all lit up? That's power going to the mobo.
 
Turn off all power, pull all cords, allow the system to sit that way for 30 minutes, then power back up.

I couldn't agree more. I have encountered this problem more than once on many systems.

I have never found away around the problem you describe other than to re-install the windows software from scratch.

I now have a friend who has this problem, but he doesn't want to reinstall the operating system.

If anyone has a solution to this, please let me and 'HP Sucks' know.

I would like to jump in here and say I have had the same problem, however, I am using a HP Pavilion DV4 1028us and I started to receive the same message my USB ports were not being recognized. I did follow one post on here about the registry change.
 
"Run regedt32.exe and navigate to;
 
HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb
 
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC."
 
After I restarted my computer that didn't solve my problem though. I ran into this problem several time with this particular machine and found that when this starts happening I first shut my computer down and remove the battery. I then restart and remove all USB device under device manager and then shut my computer down. I then restart it with the battery plugged back in but not plugged into the wall jack. After that I let the machine find all the USB components and for some reason the USB ports start working again.
 
I'm not sure if this will work for any one else but it did solve my problem.

I have an internet cafe and so far no problems with clients plugging usb's and phones in to upload photos to facebook etc untill one client brought in a Nokia phone like every other don't remember exact model. We could not get it to open. After giving up no one else could plug any USB into three of my ports.My printers work and speakers etc. Also got the message USB Device Not Recognised. Googled for 1 week untill I finally found this thread. So I followed the instructions of unplugging my computer from the wall and I waited about 10min. After I switched everything on VOILA my USB and everyone elses is working once again. Under "My Documents" is a Folder called My Drivers. In that folder I found another folder called "Details" then another one called "USB" then "USB Unknown". In that folder are 4 documents the one says USB setup information and it is about 10 pages long stating all the information about the Noikia Phone I was trying to install.
It does state that "This file contains usb descriptions of USB Hubs and composite devices. I think that these filders are on my PC because I use "DriverMax" and "Driver Detective" so one of them must have put that "My Drivers" folder on my PC which has helped. I am very happy to have solved my problem. Thank you very much. I WAS LOSING MY MIND. Now I am a happy googler.

I face the same problem. My computer is Sony Vaio laptop with Windows XP.
I connect printer, scnner and mouse via USB port. printer and scanner worked fine. I added mouse few days ago. Even mouse worked fine until today. Today all of a sudden mouse didn't work and the error message pops up every few seconds.
 
I tried to use the method explained in below thread. I find out that there are many usb related subdivision on left pane. They are: usbccgp, usbehci, usbhub, usbprint, usbscan, usbstor, usbuhci, usbvideo,
 
Which folder should I use to create the mentioned key?
 
PS) Error message appears even after plug out of all usb ports
 
Looking for your reply.

Thanks for the info.
 
It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
 
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
 
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
 
Run regedt32.exe and navigate to;
 
<span style="font-style: italic">HKEY_LOCAL_MachineSYSTEMCurrentControlSetServicesUsb</span>
 
Create the <span style="font-style: italic">Usb</span> key if it doesn't already exist. Under this key, create a new DWORD value called <span style="font-style: italic">DisableSelectiveSuspend</span> and give it a value of 1. Then restart the PC.
 
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying <img src="https://www.ntcompatible.com/public/style_emoticons/default/smile.gif" alt="smile" title="smile" height="15" width="15" />.
 
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
 
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
 
1. <span style="font-style: italic">USB peripheral devices</span> (printers etc.)
 
2. <span style="font-style: italic">HID and/or Composite USB (Human Interface Devices)</span> You're using PS/2 input devices so you may not have this entry.
 
3. <span style="font-style: italic">USB Root Hub(s)</span>
 
4. <span style="font-style: italic">USB Host Controller(s) (Universal or Enhanced Host Controllers)</span>
 
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
 
Hopefully some of this may be of help, let us know how you get on.
