Windows XP SP3 does not recognize USB Mass Storage

only detect Kingstones 128mb flash USB can be detected, other USB undetected. already install all usb driver and chipset driver also. Previously the PC set prohibited use USB flash disk and alredy formated the windows from win2K to windows XP, but the problem still happen. As my friend advise, please follow below steps: http://forums.windrivers.com/showthread.php?t=62208&page=7.

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\

Add following key: HKLM\Local_Machine\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.

After doing above steps, restart your PC. Now Windows should recognize your mass storage and should do an autoplay.

5. Some posts also mention that turning off the system and pulling out mains power supply and batteries for 30 mins is also helpful to resolve above problem.
