Windows 7: USB ports/devices stop Working when Windows 7 Boots

USB ports/devices stop Working when Windows 7 Boots

I have a HP Pavilion P6204Y Special Edition running Windows 7 Home Premium x64 that has been having issues with the USB ports for the last few weeks.
I am using a USB keyboard and mouse, which both power up/light up as soon as the computer is turned on. They work fine when I enter the BIOS, but as soon as Windows starts loading, the keyboard and mouse turn off and stop working. USB memory stick and any other USB devices totally don't show up at all either, the computer doesn't even notice that a new device has been plugged in.
I attached a PS-2 keyboard and it worked fine and I was able to go to the device manager. I checked and all the USB drivers were installed and reported that everything was working correctly. I uninstalled them all and then restarted the computer, same thing happened again.

I used the PS-2 keyboard again and ran a system restore to 5 days again (May 10). After the restore was done and the PC restarted all the USB devices worked again.
*(This is the second time this has happened now. The same thing happened on the 8th of May and I fixed it with the same procedure.)

Hi,





Unplug the device and perform the following steps until the device is detected:
  1. Restart the computer.
    Plug in the device and wait 5 seconds. If the device is not recognized, unplug it and go to the next step.
    Click Start , and type Device Manager into the Search field.
    Click Device Manager from the results.
    Device Manager opens.
    Double-click Universal Serial Bus Controllers to expand the list.
    Double-click a USB Root Hub , click the Power tab, and then click Power Properties (if it is shown). Devices that are attached to the hub are shown as well as the power that they require. If the total displayed power is over 500 mA, remove the devices and use a powered hub.
    USB Root Hub Properties showing two devices using 198 of 500 mA

    Continue looking at the power properties of each USB hub. If the total Power Required exceeds the Total power available for the hub, then remove a device on that hub to lower the Power Required number.
    Plug in the device and wait 5 seconds. If the device is not recognized, unplug it and go to the next step.
    Remove high-speed USB cables that are over three meters in length and use high-speed cables that are shorter than three meters.
    Only use high-speed cables shorter than three meters in length with high-speed USB devices (Multifunction devices, scanners, and cameras).
    If the USB device is connected to a USB port on a keyboard, unplug it and plug it into a USB port on the computer or into a powered hub.
    There may be an issue with the USB port. Try plugging into a different USB port. If the USB device displays in Device Manager after plugging the cable into a different port, then uninstall and reinstall the USB device software driver
Cheers

usb power usage low

I followed the previous post. There are only two devices plugged in right now, the keyboard and the mouse.

They are on separate hubs. The mouse is using 98Ma of 500Ma, and the keyboard is using 70Ma of 500Ma on it's hub.

I may have found the culprit. I think the problems is with the Windows 7 SP1 update. Every time I ran a system restore it uninstalled a few updates, and then I guess they would reinstall and then I suddenly had the issue again. I now installed the updates one at a time to see if any were causing the problem. The last update was the service pack, and after installing it suddenly the USB shut down again. I guess I will just do another restore and keep Windows from installing the service pack.

As I suspected the issue was with the Windows 7 SP1 update. I restored the system to the restore point created immediately before the update, and now the USB devices worked again. I have selected 'hide' to prevent windows from installing the update again, and hopefully everything is good to go. I would consider the issue resolved.

Thanks for the feedback, however, Im curious as to why SP1 causes this issue
and also it is leaving you without SP1 installed which helps with stability.

Have a look at this Microsoft article, might be worth a try?
