Mass Storage devices not showing up on Windows Explorer

I have repaired a Windows XP Sp2 Instalation, but after that, I cannot get USB Mass storage devices (USB MSD)to work. Everytime I plug in a USB MSD I hear the sound that I pluged in a new device, the remove safely icon shows up, the pendrive lights Up but no drive apears on Windows Explorer.
If I go to the Disk Management, I can see the Device, but when I try to assign a drive letter, it fails (nothing happens). With some devices I can click on the partition and then click OPEN, and that works.

I don't know anything about partitioning or Disk Management but here are some possible USB solutions:

Remove all USB drivers with:
https://filedb.experts-exchange.com/incoming/ee-stuff/6853-RENEWUSB.zip
, let it reinstall them, delete the "UpperFilters" and "LowerFilters" registry values from:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
, check:
http://support.microsoft.com/kb/925196
and the "SIMILAR PROBLEMS AND SOLUTIONS" section, and run:
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbstor.inf

After doing that, problem persists.
On device manager, there is a USB MASS STORAGE DEVICE with a exclamation mark, If I double click it and on descriptions it says  the device cannot be started

I was surfing on EE and found someone with a similar problem (usb modem) and I suggested that he used a diferent USB port. So I thought to myself, to try too.
The problem persisted, but after installing a PCI USB CARD, it worked!!
I would like to fix the problem for the onboard USBs though, since before the windows repair they worked fine.

Did you try uninstalling the driver and reinstalling it?

It might be a driver problem. Did you go to the website and look for driver updates?

I dont want to reinstall because there are too many softwares and configs.

try updating the chipset driver
these can help too :

3- run this from the run box (you can copy the command) :
rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\WINDOWS\inf\usbstor.inf
or :start>run>services.msc
look for Removable Storage Service. Is it set to Auto, and if not started, click the Start link in the top left...
In c:\windowsc:\windows\inf.  look for usbstor.inf -  If not found, copy from another PC. If you find it, right click it and select Install
See if it rebuilds the USB support...  normally located at c:\windows\system32\drivers
4-Start the Registry Editor (Run -> Regedit). Check if under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion the item 'DevicePath' points to '%SystemRoot%\inf'. Additional items, separated by semicolons, are ok but '%SystemRoot%\inf' has to be one of them.
Then delete the file C:\WINDOWS\inf\infcache.1 - XP will recreate it.
The INF folder and the infcache.1 file are 'hidden'. To see them in the Windows Explorer:
Menu 'Tools' -> 'Folder Options' Tab 'View', mark 'show hidden files and folders'
5-The registry keys reside in the registry (click start, run, regedit) under the following keys:
 
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetEnum
edit: (Slashes may not appear in this forum for some stupid reason...)
It is: HKEY_LOCAL_MACHINE, SYSTEM, CurrentControlSet, Enum
 
Under the headings USB, and USBSTOR. Right click "USB", click "permissions" click the "Allow Full Control" checkbox, and OK. Once you have completed this, right click the "USB" key, and click delete. Do the same for the "USBSTOR" key, delete both.
 Restart the PC, . After this has completed, plug your USB Jumpdrive back in, and it should recognize.

If it still doesn't work after a restart, the files in C:\WINDOWS\inf might be corrupt. A Windows repair install should correct this.

Tried nobus solution but it did not work.
The motherboard is an AM37 and uses VIA chipset.
I have tried updating the drivers, I tried the newest VIA 4in1 driver, and I it was Windows Repair that started this mess in the first place.
Nothing works.
I remember seeying somewhere that some botherboard have a jumper to set a diferent voltage for the usb +5. Does anyone know what that is and if it aplies here ?

>>   a jumper to set a diferent voltage for the usb +5.   <<   as far as i know there is no other voltage possible - the standard is  +5
can you still use a system restore? that can help too, if the restore points are not wiped by the repair..
otherwise, a fresh install always cures this problem

tarcisAuthor Commented:
I cant use system restore cause I turn it off for better performance.
I am avoing a fresh install because there is too many stuff to save configurations, software to reinstall that I dont even have the CDs anymore, and games with saved data....

nobusCommented:
everybody tries to avoid a fresh install; but it is not necessary.
you do it once, and sacrifice the time needed to install all programs, updates, and whatevers
THEN you make an image of your disk, that you can restore in 10 minutes !

Well, I tried a XP REPAIR and here are the results :
Right after the repair my onboard usb started working again
But the problem with the drive letter persisted.
AND my AGP Geforce 2 was not detected (during the repair it asked for a viaagp.sys which I didnt have)So I tried installing the old via 4in1 driver.
By doing so, my geforce was detected but the USB stopped working (everything I plug in, detects as unkown device)

If I remove the VIA CPU TO AGP from device manager, the USB works again but I am left without my AGP Geforce!

Seems there is a problem with the via chipset driver.  (a conflict with the AGP driver and the usb) HOW IS THIS POSSIBLE ?
I Tried the new Hyperion drivers, but USB does not work at ALL with any of the via drivers.

HELP!!

tarcisAuthor Commented:
Ok, I think the conflict is with my geforce nvidia driver.
If I use the onboard video, usb and sound drivers work fine.
After pluging in my geforce, not only the USB but the sound stops working also.
I understand this might be a new question, but the problem with drive letters persist excluding my geforce problem.

tarcisAuthor Commented:
The correct word is DESPITE, not excluding.
I am using the latest nvidia driver available : 93.71_forceware_winxp2k_international_whql

But I have tried older drivers with no luck
Here are the ones I also tried:
84.21_forceware_winxp2k_international_whql
53.03_winxp2k_international_whql
4523_whql_WinXP-2K

The mainboard is a FIC AM37.
its an Athlon XP 2000+
with 1gb memory SAMSUNG (memtest passed)
40gb MAXTOR HD (seatools long test passed)

I am currently using an offboard
PCI Sound Card (since sound is not working)
PCI USB CARD (VIA)

nobusCommented:
the usb driver is included in the chipset driver
you can try this for restoring the usb :

Remove all USB drivers with: https://filedb.experts-exchange.com/incoming/ee-stuff/6853-RENEWUSB.zip ---> Now reboot and test.
Delete the "UpperFilters" and "LowerFilters" registry values from:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

tarcisAuthor Commented:
I managed to get the AGP and the USB working by enabling the Onboard sound (sound is not working), and using the sound from my PCI card.
I have discovered another thing
If I assign a drive letter in disk manager to my pendrive, I still wont see it in the Windows Explorer or "My computer", and even if I type V:\ in the address bar (V: being the assigned letter) it gives me a cant find file:///V://............
BUT if i go to the Command Console and type V:
I can "dir" and see all my pen drive contents.
Weird or what ?

tarcisAuthor Commented:
by the way
There is NO upper and LOWER keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}

nobusCommented:
did you remove, or install the AGP card?  if not remove the software - test usb, reinstall agp card again and test

tarcisAuthor Commented:
The problem with the drive letters is not related to the AGP (it persists on all cases)
But I was having a problem with the AGP and USB, in that case, the USB woudnt work at all.

Any more ideas ?
Problem persists...
When I plug in a USB Stick, it recognizes but no icon is created on MY computer, or windows explorer.
The only way to access it is be disk management, but even after assigning a drive letter, the drive does not appear. I am able to access the files in it by right clicking the partition in diskmanagement and selecting OPEN

Thank you all for helping, none of the solutions worked, only a fresh install will correct this, but that wasnt the answer I was looking for. I have split points for those who were correct and who helped most. Thanks
