It allows you to intercept and inject messages at that point. You can use it when you want to access a device for which you don't have knowledge of the driver API.<br> <br> David<br> <br> <div class="moz-signature"><span style="font-style: italic; color: red;">My email address has changed.

I dont believe I have it installed but I am using libusb just fine (I think I only have the device driver installed). I couldnt find on the website what the difference between these two drivers is. I have a current prototype using libusb to issue SCSI commands to a mass storage device arbitrarily. This works great, but now we need a way to actually issue these commands during standard Mass Storage requests (read/write etc of a flash drive, for example). I do not see how I could access to these in python (or user mode in general) - so I believe my best option is to create a filter driver to modify the SCSI requests as they go down the stack. Does this sound right? And if so, is there some kind of interface directly into the libusb filter driver that I could use?
