Is it really two interfaces? Or is it one interface with two alternate settings?

No. Vendor requests have nothing to do with vendor-class devices. You can have vendor requests even on standard class devices. My blind guess is that you were trying to claim interface 1, when you should have been claiming interface 0 with alternate setting 1. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
