There are two signing requirements in Windows. The KMCS (kernel mode code signing) requirement will prevent a driver from being loaded unless the driver or the driver package is signed. This check is done every time the driver loads, but is only done on the 64-bit systems. Since you are using Microsoft's driver, which is already signed, this is not a problem for you. The PnP check is done when your driver is installed. This is what puts up the dreaded "unsigned driver!" warning, or the less dreaded "do you trust this publisher?" warning. This check is done on all systems, but ONLY at installation time, and as long as the user agrees to the dialog, things proceed smoothly. So, as long as you know you'll get the "unsigned driver" warning, your driver should work fine. Note that Windows 8 now requires a CAT file for all driver packages. Look up the "inf2cat" tool. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. ------------------------------------------------------------------------------ Everyone hates slow websites.
