Error 1168

NTDEV

i all,

As I said earlier, am invoved in creating PnP for a driver package ( Using windows default driver “UsBSER.sys”) and with DPInst.exe.
Since USBSER.SYS is not required to sign and i am getting warning during the installaion of driver(due to unsigned inf).

After installing the driver at first time, If i unplug and re-insert the device in another port , windows finds the correspongding inf from INF ROOT directory and tried to load but it fails due to the error 1168.

Below is my setupApi.log :

So, i am restricting the user to use the single USB port to avoid multiple installations and am not able to achieve pnp mode of installation.

But in later versions of windows,it can load the driver even if its unsigned and am not prompted to install the driver more than once.

Note : With Test certifiactes signed for inf alone (not for drivers) and insatlled our driver package is working fine in all the versions of Windows including windows xp.

This should be on my “frequently requested answers” list.

There are TWO separate and very different signature requirements for
Windows drivers. The simplest to understand is the KMCS check, which
happens only on 64-bit systems. Your driver will not load – ever –
unless either the driver binary or the CAT file is signed with a valid
class 3 code-signing certificate. This check is done every time the
driver loads. For this, the Microsoft signature in usbser.sys works fine.

The other check is the install-time signature check that is done when a
driver for a PnP device is installed. This is done ONLY when a new
device is detected and a driver is chosen. This signature MUST be
present in the CAT file, and covers the entire driver package. The only
way to completely satisfy this check is to have your CAT file signed by
WHQL.

The warning you are getting is because your CAT file is not signed by
WHQL. Unlike KMCS, this warning can be dismissed, and it will not be
checked again until a new device appears.
