From: Brausewetter, Kurt on 15 Sep 2010 05:02 MSDN: ReferenceString [in, optional] Optionally points to a UNICODE_STRING. The string must not contain any path separator characters ("/" or "\"). Function drivers typically specify NULL for this parameter. Filter drivers must specify NULL. Filter Drivers must specify NULL => That's a Problem or can i take a Non-NULL ReferenceString? "Maxim S.

You cannot define 2 device interfaces with the same GUID and same ReferenceString. -- Maxim S. Shatskih Windows DDK MVP maxim(a)storagecraft.com http://www.storagecraft.com

OK, i Test BTW: But what the F**k is that in MSDN: "Filter Drivers must specify NULL" "Maxim S.
