- kbd filter driver not loading
- Posted by clackmannan on July 14th, 2005
I have a keyboard filter driver that has load problems on a W2k Sp4
machine; sometimes it loads at boot time, sometimes it doesn't.
I can use /BOOTLOG and look in NTBTLOG.TXT to confirm if it's loaded or
not, but I can't find anything that will tell me why it's not being
loaded. Any hints?
TIA

what happens when you boot under a debugger? do you see your driver
loading? are you filtering a ps2 device? if so, the ps2 driver (i8042prt)
may not find a device so it will unload the keyboard stack.

Sorry. Yes, it's a PS/2 device, and it is connected at boot time.
We can't repro this here, only in the field where there's not the
ability to attach a debugger. I was hoping there was something like a
registry entry I could configure or a DDK utility I could run to tell
me why it's failing to load ?

nope, sorry. you might try to look through the event viewer for events from
the SCM or i8042prt

if this is a pnp class filter driver, you will be loaded on every keyboard
regardless of the phase of boot.
