hidusb filter driver

[b***@gmail.com]

Hi,
I'm running into problems with a filter driver that I install as a
lower filter under hidusb. I've had a setup working ok forever. But
now with a dual core machine running XP sp4, unplugging a hid device
risk to create a BSOD somewhere, with a CORRUPTED_POOL bugcheck.

I've tried replacing my filter with the one from W. Oney's book. Same
thing. It seems the filter never gets the IRP_MN_REMOVE, but only the
SURPRISE_REMOVE.

I'm looking for people having experienced something similar or know
something about the hidusb under MP machines or any clue on how to
debug further.

thank!

enable driver verifier on your driver and repro. the bugcheck also gives
you the pool that was corrupted, it up to you to look at it and figure out
what you are doing.
