I want only my driver’s DbgPrint s to appear in WinDbg. How to achieve this?
Is there any option ?
Not really, as far as I know.
Obviously, if you want to KNOW which is your debug prints, as opposed to
other products, you could just add a prefix, say “MYDriver: This is my
message”. That would help you know that it’s your debug prints.
If it’s for logging purposes or such, you could also log the debug output,
and then filter it with something like grep, so that only the text starting
with “Mydriver” is printed.
[Or you could patch the other driver files so that they don’t print
anything…

If you use a standard format for all your messages, you can use .ofilter in
WinDbg like this:
.ofilter “*MyDriver*”
That will only display output with “MyDriver” in the string.

Heh. Had a user bring up dbgview on a system yesterday to debug some stuff
in a MIDI driver of mine. As soon as he started dbgview it started saying
“hoho”. Yep, hoho. About every 200us. Continuously. And no, that ain’t
my driver.
Turned out it was a commercial driver from a rather well-known company that
mostly makes Mac hardware.
Sigh…
Filtering quickly saved the day from that abortion.

Loren,
I think you have found a bug. Please contact them or give us their
name, so that we (the list) can contact them.
It definitely must read “oh no!” not “hoho”. 
Norbert.
“Take my advice, I’m not using it.”
---- snip ----
Maybe they outsourced it to the North Pole ? Some Elf may have forgotten the
extra “ho”, that’s definitely a bug.
Actually, I have a problem: if I load a crash dump file and type “!analyze
-v”, I can’t load another crash dump file any longer, it keeps saying that I
don’t have enough storage to complete the operation (“Win32 Error 14”).
Looks like there’s a memory leak somewhere ?

Sadly, these people are very good in the Mac world and very clueless in the
PC world. Complaining about their broken MIDI drivers has had little or no
effect in the last 10 years or so. OTOH, their newer audio drivers are
pretty good.
I don’t think I’ll mention their name in public here, but if you know
anything about MIDI hardware, there are only about 2 companies that make
MIDI interfaces these days, and one of them is a long-time Mac hardware and
software supplier…

Find a call to DbgPrint(“hoho”) in the driver’s assembly and replace it
with NOPs.

And once you’ve done that, send the repaired driver back to the
manufacturer.

Hard to do when on the end of 4,000 miles of telephone wire to a user with
no debug tools other than dbgview, which he had never seen before.
Filtering saved the day.
