problems in attaching to USB removable drives

Hi,

I have a legacy file system filter driver on windows XP and I am facing
problems in attaching to USB removable disks.

I have tested SFitler to see if attaches to dynamic USB removable disks by
put debug messages in Sfilter in SFNotification and
SfAttachDeviceToDeviceStack functions but I do not see any messages.

I am doing something worng, any information could be of great use.

thanks,
Kedar.
