XP USB Drive not detected or installed fix

[prashantisonline]

Problem:
Windows XP does not recognize USB Mass Storage Drives
Device is detected and listed with an exclaimation mark in Device Manager

Solution:
After spending hours on internet and reading through numerous posts, I found

following solutions which will definately work (as they worked for me):

1. Delete following file: windows\inf\infcache.1

2. Go to windows\inf folder and see if you have read/write permissions for

following files:
usbstor.inf
usbstor.pnf
If not, open security settings for above files and add your username for

read/write access.

3. Open registry editor and:
Delete following keys:
HKLM\System\CurrentControlSet\Enum\USB\ <read all keys and delete all those

saying USB Mass Storage Driver>

Add following keys:
HKLM\System\CurrentControlSet\Services\Usb
Add a new DWoRD Value and name it "DisableSelectiveSuspend". Give it value 1

4. Make sure you have USBSTOR.SYS file in your windows\system32\drivers folder

(It wasn't there in my case). Just Google using Usbstor.sys and you will find

the file to download. Save it at above location.

I did this on my daughters computer and it worked great.It was my first time playing around in the registry,I built another pc for myself,just for music in the living room,and had the same problem.I copied and pasted the USBSTOR.SYS into the windows/system and the windows/system 32 folder on this pc,then tried my usb drive.IT WORKED.Don`t know why,and i`m not going to question why.I didn`t have to play with the registry or anything else.Maybe i just got lucky,or stumbled onto something that is so much easier.Don`t know,but the next time i build another pc and have the same problem,i`m going to try it again.If it doesn`t work on my next one,i`m definitely going to use your method again.Thanks so much,for the detailed info you gave.

is every number a single solution, or do I have all four steps?

'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr o l\Class\{4D36E980-E325 11CE-BFC1-08002BE10318}

There should be a upperfilter in this directory, but there isn't. What is wrong?'

There 'might be' a filter - not always - I don't have one.

That is just a thing to check - some installs and some additional things installed may put a filter there - that's why you check for it.

That second post is a four-step checklist of things you want to do and check on.

Did both things, no success

Is this hopeless you think or do you have any other ideas?
