Keyboard Filter and Unspecified devices

I have a keyboard input filter driver which, like the keyboard filter sample
in the WDK, creates a raw PDO that I use to communicate with the filter from
user-mode. The sample names the device “Keyboard_Filter_”.

The problem is that this device name shows up in the Windows 7 Devices and
Printers window under Unspecified devices. This is confusing some of my
users since they don’t know what the devices are for.

Am I installing my filter incorrectly or is this just an unfortunate side
effect of creating raw PDOs?

Are you marking the pdo as removable or surprise remove ok? See if not setting either of those fixes the issue.

Yes, it’s marked as both Removable and SurpriseRemovalOK. Setting those to
false won’t have any effect on being to uninstall the device without a
reboot, right?

Shouldn’t. Sr ok means you can report it missing without UI telling you you should stop it first. Removable means it is a new distinct piece of he that can be removed from the parent device
