Dear sir,

My name is hardik.
1>I have Windows XP SP2 installed in my computer; of lately whenever i connect my Pendrive (Transcend Jetflash 2GB) in USB slot the LED on device glows momentarily only; the taskbar also shows USB device connected but my pendrive is never detected in my computer.

2>Initially in device manager in USB controller it showed a yellow exclamation and code 10 error in device status but now its gone!!!!!!!! Instead now it shows no drivers installed for usb mass storage .

Hi,

try this 1,

Click on start-->run ----> type diskmgmt.msc and click on OK. If you can see

your USB drive partition, just right click on it and select change drive letter and

paths --->then assign different letter for you usb drive.

If the problem still exists then try this 1,

1) Click on Start-->Run--->type regedt32 ----> click on OK ----> registry editor will

be opened.

Note: Backup your registry by clicking on File--> Export.

2) At the left side, navigate to this location

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\

{4D36E980- E325-11CE-BFC1-08002BE10318}

At the right side, delete the file named UpperFilter.

3)Now Navigate to this location

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\

{4D36E967-E325-11CE-BFC1-08002BE10318}

4) At the right side, delete the file named LowerFilter.

Then close the registry editor and restart your PC.
