Subject: Filtering USB storage data in kernel module

Hi All,
I need to filter  the data written/read to and from the USB storage 
disk. Now the way USB is made known to OS is through SCSI and then 
respective filesystem ( mostly usbfs).
So is there any way I can intercept this stack and have my kernel module 
invoked so that I will get the data.

I have been thinking on two approaches:

1. Use VFS and write a proxy filesystem for USB device which will filter 
the data.
2. checking SCSI and any intercepting point.

I am currently looking at USBMONITOR source code as well.  Please let me 
know if there is any other way to achieve this.

Regards,
