Two Lower Filters
in [Device Drivers]

From: uba on 29 Jan 2010 06:21 Hello, I have vendor provided USBSTOR lower filter. I wanted to add my filter driver below the USBSTOR lower filter. I actually want to filter the requests further. I'm not sure if this is possible to have two filters one below the other, but I just wanted to check on this. Thanks nd Regards, uba
From: Don Burn on 29 Jan 2010 08:15 You can have as many filters as needed in a given location. You cannot guarantee that your filter is immediately below another filter because some other filter may get there first. -- Don Burn (MVP, Windows DKD) Windows Filesystem and Driver Consulting Website: http://www.windrvr.com Blog: http://msmvps.com/blogs/WinDrvr Remove StopSpam to reply "uba" <kid07.uba(a)gmail.com> wrote in message news:d3f3670e-ffa0-4fef-86f6-be7c061281c0(a)m35g2000prh.googlegroups.com... > Hello, > > I have vendor provided USBSTOR lower filter.

Also, I cannot add "LowerFilters" entry into registry as this entry already exists with other driver. How can I add my filter driver in registry. Thanks nd Regards, kid
