USB's Drive Not assigned

Connected a different USB but same thing happens... appears in Device Manager as unknown device and requires the driver to be updated.

Ok this should be good as the driver has been deleted for this drive did you try updating the driver?
Another option may be to visit the manufacturers websites and see if you can download windows 7 drivers

Sorry for the delay, I have been trying to find answers to your problem. I am working on the message you received "The operation failed because the disk management tool is not up to date. Refresh the view, Close the disk management or restart the PC" Unfortunately I have found no definitive answers.

Firstly I think you should run Disk Check from step 4 go to step 8 then check the drive to see if it is now recognised

If the above does not work A more drastic answer is to delete and format the drive You will have to make a copy of all data on the drive as all data on the drive will be erased
Disk - Clean and Clean All with Diskpart Command

I would try these methods with just one of the affected USB drives to find out if it is going to help or not.

The problem seems to be that windows either does not load a driver or tries to load the wrong driver, In the research I have done Microsoft seems to lay the blame rightly or wrongly on the drive manufacturers and suggests that the drivers for the devices should come from them. We both know that the drivers are included in Windows but the problem is how to make Windows load the right driver for the right device. Up until now the tutorial I posted has had a fairly high success rate in solving this problem but I am unsure what to do with the unsolved cases.
At the moment the only help I can give is the tutorial, that should, by the way be carried out on each affected PC ( I forgot to mention this before) and from my own experience I suggest one device per USB port as only one driver will be installed for each port avoiding Windows trying to load the wrong driver. Or even buying all devices from the same manufacturer.
I am at a loss as to what else we can try but I will continue looking for an answer and will let you know if and when I find one.
One last thing, do you use a USB hub? if yes is it powered? I cant verify this but I have read about similar problems where USB hubs that do not have a power supply are being used.

I have just found this, It may possibly help you;


Click on C:\ and create a folder called USB drivers

Go to C:\WINDOWS and copy the contents of the folder called inf

Paste the contents into the folder you just made

Then when you get an unrecognised USB device in Device Manager point it to the folder that you have made on C: and see if it gets remembered this way
