I have a PC which does not allow me access to any removable storage device, USB memory stick, external hard or anything.
when I plug the device in it appears in my computer but when I double click on the device it says "Access denied"
this devices work fine on all other PC's and I have also tried it under a different profile on my PC but that does not work either.
It seems to me like a registry issue or some driver issue but not sure what and where to look.
Everything seems well in device manager.
Dont really want to re-image the PC with a fresh OS as I will have to spend a whole week just installing software and stuff.
Any ideas????
thanks

Houssam,
I ran both scans and a few things were found but the problem still exist so I below are the results of both scans (bottom of this post)
Shariff,
I found that post the other day and i have tried most of those thing - I do think is most like drivers or registry but not sure what I need to in order to fix this
this might be interesting - the USB drive does appear in the Computer management console under "Disk management"
When I check the hotplug.xml file in C:\windows\System32 nothing appears to have been detected - normally what should and used to happen is when you plug a device in an entry for the device is added in this file
here are the logs for both scans

 thanks guys
I couldnt find those 2 keys in the registry - could this be the issue that they dont exist.
How do I add them in (I mean where exactly) - if both these keys are needed could you provide step by step instructions on how to add them.
thanks for the reply

First, you want to rule out any problems with the device itself. A good way to do this is to plug the USB device into a different computer to see if it works there. If it does not work in a different computer, then the problem is with the device itself. USB devices, although very handy and portable can fail just like any other device.
However, if the USB device works in another computer system, then the problem lies with the configuration of the computer where the device did not work.
Follow the steps below to troubleshoot this scenario and make your USB device work again.
1) If you are using a USB cable with your device, check the cable to make sure it matches the speed of the device. Use USB 2.0 cables with USB 2.0 devices and USB 1.1 cables with USB 1.1 devices. Swap cables and check the device, if this does not work, proceed to Step 2.
2) Next, open Device Manager and look under the heading for USB Serial Bus Controllers. If there is a device with a yellow exclamation mark next to it such as USB Mass Storage Device. Double-click on the entry and check the Device Status. If the status shows something like
"This device cannot start. (Code 10)"
proceed to Step 3.
3) The easiest way to solve a USB error code 10 in Windows XP is to follow the steps below to remove and reinstall all USB controllers.
A. Click on Start
B. Right Click on My Computer, click on Properties
C.Click on the Hardware tab
D. Click the Device Manager button.
E. Expand Universal Serial Bus controllers section.
F. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
G. Restart the computer, and allow the computer to reinstall the USB controllers.
H. Plug in the removable USB storage device, and then test to make sure that the issue is resolved.
wow - really appreciate all the help,
Houssam - I ran the script but  still getting the access denied message - what does happen is USB stick are detected faster than they used to be which is a good thing but still "access denied"
Micheal MCDST
The USB's do work on other Computers so that is definately not the issue here - everything points to my local system#
all these devices used to work about a month ago - and then I started getting problems but never really got time to work on it. most of the devices plug directly into a usb port without a cable
I also uninstalled all the usb host controller and restarted but still getting "Access deinied message"
I am aware of the drive letter assignment issue but this is not the case as a drive letter is assigned to the memory stick/s
My suspitions are also on the drivers or a corrupt/missing registry key but not sure where to look

The absence of the USBSTOR registry values might the indication of the problem.
I am attaching the screenshot of the key how it looks like on my computer.
In case if it's just a Start value missing you could copy the following lines to notepad and save it with .reg extension, then double-click on the file and this value will be entered to the registry.
However, if all of the values are missing you might enter it in the registry by hand, based on the screenshot.
Hope it will help
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM
"Start"=dword:00000003
After uninstalling all the USB host controllers and restarting it seems like UBSSROR has come back and it looks exactly as the pic you have attached.
Once thing though - in your earler post with the entry
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM
"Start"=dword:00000004
I couldnt see this in your pic or in my pic anywhere - do I need to add this in, if I do - should it do it manaully by right clicking\New\Key or by adding the lines into a a notepad files - save as .reg and double click?????

Igor
I have scanned for viruses and malware - but that didnt fix it
I am still getting access denied on all USB storage devices
Any further suggestions?
Regards

Any chance you are the "victim" of group policies or local security settings?
You mentioned that the attached USB is visible in Disk Management. Could you provide the screenshot? Ideally, if it will also show the exact error you got.
Thanks

I didnt think of group policy - I shouldnt be as I am a member of Administrators group and other admin can access USB stick and they are using the same model PC's
Have you tried to access E: drive from the command prompt? If not, could you try?
Are there any other registry settings that I need to check maybe?

2. Have you tried to reformat the attached USB?
2. Any software present that might be locking down the access to USB?
To discover if a problem is caused by 3rd party software first start XP in Safe Mode. If the problem is gone then, boot again normal. Go to Start -> Run, msconfig, Tab 'Services', check 'Hide All Microsoft Services'. Disable them all, reboot and check if the problem is gone again. If yes, then enable them one by one (reboot each time) until the problem is back again. Then you have the culprit...

here the the replies to you Q's
1. Â this key does not exist in my registry
2. Its not a problem with the key as all 3 work in my colleagues PC - who has admin privelages myself
3 Â There is software we use to block access to certain devices for certain groups of users. Â We us Device Wall Control - however - I am a member of Admin and have full permission for all devices so I dont think it is - just to make 100 % sure, I removed my network cable and restarted the machine - logged in local admin and it still didnt work.
I also did what you suggested and started in safe mode - but the USB wasnt detected at all - I dont know if safe mode completely disable the USB services and drivers???? Â I also restarted and disabled all non microsoft services but this didnt solve it either.
thanks once again - I really appreciate your help
Regards
A very interesting and strange thing just happened - I was trying a few things and started the PC in safe mode - As nothing was appearing in My computer - I checed the Disk management console and saw the USB stick mapped to the E drive so I thought let me try and open it using the Run dialog box and what do you know - it worked :)
So then I logged in as normal and put the same USB key into the PC and hey presto - it opened through both the run dialog box and my Computer. Â So here I am jumping out and down thinking the problem has been solved. Â So I tried another USB stick and that didnt work - thinking it might be the stick now I tried the one the worked previously and that stopped working as well.
this now has mee really baffled
any ideas???????
Regards
Naz
i will check that out and get back to you - also I noticed another strange thing - I have a removable Western digital hard drive - when I plug it in I doesnt show up in the disk management cosole and when I check device manager - there is an exclamation mark again one of the HID compaint devices - when I right click and the status says "no driver".
but this used to work fine a month or 2 ago - it crashes when I try to uninstall it and after removing the WD hard drvie the PC doesnt even detect any other USB memory stick until I restart
Thanks once again
Regards
