Need help with signing inf-only driver installs.

Hello.

Our company makes several simple non-isochronous USB devices that we talk to
using the winusb.sys driver. Our installer package consists of only an INF
file and the various microsoft co-installers required for making sure winusb
is installed properly.

We want to pre-install our INF file using DPInst.exe so that when one of our
USB devices is plugged in, the driver will install without any user
interaction. This, of course, requires that the driver be signed.

My questions:
What is the simplest path to achieve this goal?
Do I just make a .cat file with makecat and sign it with signtool or do we
need to go through WHQL?
If we need to go through WHQL, do we need to go through all of the HCT
hardware tests, or is there a fast-track for INF-only installs?
Will one signature work for XP32, XP64, Vista32, and Vista64?


We are currently waiting for our VeriSign key, so we can try it out.


Thank you
Scott Wild

It requires that the driver PACKAGE be signed.

If you want a silent install, you must go through WHQL. There is no
shortcut. If you sign the package yourself, you'll get the "Do you trust
software created by Company Xxxx?" dialog.

HCT is no longer applicable. You must use DTM -- the Driver Test Manager
-- part of the Windows Logo Kit. DTM requires a significant investment in
hardware, software, and personnel.

If your device falls into a standard device class, you must pass the DTM
tests for that class. If not, there is an "unclassified" device category
which is somewhat simpler.

When you submit the kit, you tell them which operating systems you need.

Is that true? I thought you could choose "Unclassified" no matter
what, as long as you don't care about getting a logo.

I've been looking at this, WHQL still allows ths for desktop devices, but
has withdrawn this for server devices.
