Signing a device upper filter driver

Hi,

I do hear from many diffrent places that filter driver do not need to pass
WHQL. but how can I get them sign ?

Just to make myself more clear , when I do go to the device manager and
looking in the driver tab of one of the devices I can see that
their are filter drivers that do get the sign icon. but my filter do not
have a sign icon.

I do have a very limited knowlage regards driver signing, the more I am
getting into it, the more I am getting confused :).

Any help will be appreciated.

Not sure where you heard that. Our mouse device upper filter driver is
WHQL’d.

Loosely speaking, WHQL’ing doesn’t depend on whether your driver is a
filter or function driver, it depends on what kind of device it is.

You can’t get a WHQL signature for device classes that WHQL doesn’t
support, so you may be out of luck there. However, at least in principle
you can get a DQS signature for any device class that WHQL doesn’t
support. That’s not strictly “WHQL”, but it’s a Microsoft signature.
