Solved: Driver keeps trying to install
I was having trouble with xp recognising a usb flash drive

Ended up altering stuff in the registry - even though I exported the changes first before deleting (and subsequently importing them back in)

Now 2 unknown devices keep looking for drivers every 2 seconds - no usbs connected

Need some registry help I think !

And subsequent help to recognise usb flash drive

Thanks

So is the registry now back to how it was.
You do not need to alter any registry keys, in the normal course of events.
The reasons why it could not see the flash drive are

On here but to save me typing it now, as Window has just posted

When you said you exported the changes first before deleting and then importing the changes back in, you mean you did a registry backup and restore? I just want to make sure if that is what you mean't which I think it is. So if you did that, then your registry is fine.
Are any of your USBs being recognized? If NO, then you would need to go to the device manager and follow the instructions in red below:
NOW:
Before you do any of the following and if you have any other USB devices, which I think you might likely have attached to your System, take note of the drive letters being used. There is a possible drive letter conflict. Are you on the network by any chance?

THEN:
If your USB is not being recognized, I suggest removing any other USB devices that you may have plugged in and logging on as admin if you are not the admin and then clicking on start>right click on my computer>manage computer. The computer management console comes up. Now Plug in the USB device that Windows was having trouble recognizing and take note of the drive letter that the USB device is using. Go back into the computer management console and then change the drive letter of that device under disk management to something other than the ones used by the deviced that already being recognized by Windows.

ALSO:
Go to your device manager and see if you have any yellow exclamation icons indication a hardware failure. Take note of that. It may be that you need to uninstall the driver for those devices and reinstall them. Make sure your version of Windows is updated.

I thought I was doing a good thing when I did a disk cleanup to free up some space - I deleted all the system restore points except the most recent one.......

The lines I changed in the registry - I imported back in again

Anyway, items with a yellow question mark in DM are Unknown device with a ref - STORAGE\PARTITION\S9DC96E9E_O2F10C00_L129CE26E00

Another Unknown - ref - STORAGE\PARTITION\S9DC96E9E_O7E00_L2F08E00

and COM1 with a ref - ROOT\*PNP0501\1_0_17_0_0_0


Every 5 secs, a Found new hardware window comes up saying -

There was a problem installing this hardware

Unknown

The data is invalid

No usb or other devices are plugged in, and I am not on a network

When I go to DM and try and uninstall these devices, the systems freezes.....

It is a Dell 4600

  1. Click Start, click Run, type devmgmt.msc, and then click OK.
  2. On the View menu, click Devices by connection.
  3. Expand the PC node.

    Note Because Microsoft Windows is installed on computers that use different types of processors, the PC node may be named differently on your computer. For example, the PC node might have any one of the following names: ACPI Multiprocessor PC
    ACPI Uniprocessor PC
    Advanced Configuration and Power Interface (ACPI) PC
    Standard PC
  4. Expand the PCI-Bus node.

    Note If you do not see the PCI-Bus node, expand the current node, and then expand the PCI-Bus node.
  5. Expand the Manufacturer and Model Enhanced Host Controller node.
  6. Right-click the USB Root Hub node that is listed under the Manufacturer and Model Enhanced Host Controller node, and then click Properties.
  7. Click the Power Management tab.
  8. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
Additionally - do you have SP3 installed. If you only have SP2 update to SP3.

Thanks for your help

However, I am still getting "Found New Hardware" with "Generic Volume" still trying to install every time. The box says Unsuccessfull - The data is invalid

I have faith this can be rectified (somehow)

I have SP3 installed

Is there anything on the flash drive.
If so put it in another computer and format it.

Sorry - did not just spot that - drive was NOT connected.
Go Control Panel
Administrative functions
Computer Management
Disk Management
Any drives shown there other than of course your recognised HDD /s and CD DVD

Managed to get it sorted


Got info from post 12 at

http://forums.windrivers.com/showthread.php?t=49714

What this does is resets all the Permissions


Download SubinAcl from :

http://www.microsoft.com/downloads/e...displaylang=en

and put it in the folder that Post 12 suggests creating along with reset.cmd that you create with Notepad


No more windows coming up saying that it cannot install Unknown Device

and Flash USB drive can now be read


Sorted

Cheers

Pleased it was sorted.
I have to be honest I never associated permissions with altering the registry keys, which I never thought was a good idea, to correct a problem of a usb flash drive not being reognised. You clearly must have altered those (permission keys)

However, unless I am mistaken you could have done the same thing with My Computer, right click the HDD, click properties, click Security and reset the permissions there.
