Thank you so much for quick response. It is awesome. Today I have some time after regular work hours so I went to school multimedia lab and installed usbdlm under domain administrator credential. After that I log off and log in as limited domain user and started plugging in kingston drive which has never been on the computer. To my dismay, windows immediately prompt me with user name and password to elevate the credential. I cancel the dialog box hoping that usbdlm would still kick in. But it didn't help me. I check under services.msc to make sure usbdlm service is active and running. So, I unplug the kingston usb drive and plug in different brand which also has never been used on the computer under limited user account. Windows again prompt me for user name and password. So, I canceled the prompt unplug the device and plug in the different brand and the same prompt come up again. So, I don't know sdbdlm is not working or I did something wrong. Any help or suggestion would greatly appreciated. This usb devices challenge has been bothering me for a year now with no work around.
