Folks,
is there a way to enable tracing for usbehci.sys (checked version) for
XPSP2?
I’m debugging a crash on a XPSP2 machine that always happens within
usbehci.sys in the same exact spot (a NULL reference), and I cannot
understand what’s causing this (it happens in the DPC routine of USBPORT, so
my driver is not directly in the stack).
The checked version of usbehci and usbport trigger two assertions before the
crash, but I have no idea what they mean:
*** Assertion failed: !TEST_FLAG(td->Flags, TD_FLAG_DUMMY)
*** Source File: d:\xpsprtm\drivers\wdm\usb\hcd\miniport\usbehci\async.c,
line 2205
*** Assertion failed: FALSE
*** Source File: d:\xpsprtm\drivers\wdm\usb\hcd\miniport\usbehci\int.c,
line 89
Thanks!
GV
An update on this: after a morning of crashes and reboots, and different
versions of the usbehci/usbport drivers, this is what I always get from the
usbehci/usbport checked driver from XPSP3:
00007805 1:49:16 PM
00007806 1:49:16 PM *** Assertion failed: !TEST_FLAG(td->Flags,
TD_FLAG_DUMMY)
00007807 1:49:16 PM *** Source File:
d:\xpsp\drivers\wdm\usb\hcd\miniport\usbehci\async.c, line 2166
00007808 1:49:16 PM
00007809 1:49:16 PM 'xMP.SYS: 'HC asserted HostSystemError, attempting reset
Have you ever seen that assertion regarding Host System Error on the host
controller?
Moreover, I discovered that all my customers (and my test machine) having
this issue use the Intel EHCI 24CD controller (ICH4/ICH4-M).
Has any of you had problems with such controller?
Have a nice day
GV

This TD_FLAG_DUMMY problem was reported by another poster on this list 2
years ago. His problem only occurred under continuous, strenuous load.
I do not think there was any resolution.
Moreover, I discovered that all my customers (and my test machine)
having this issue use the Intel EHCI 24CD controller (ICH4/ICH4-M).
Unfortunately, this chipset is an antique, circa 2001. This may
actually have been the first Intel chipset to include USB 2.0 support.
Thus, it’s not surprising there might have been problems.

Yeah, I saw that.

I wouldn’t be surprised either. I’ve tested our hardware on a bunch on EHCI
controllers (basically from ICH5 on) and they all work flawlessy with our
hardware.
I asked the manufacturer of the chipset that we use if they have seen it
before, I’m now waiting for an answer.
Thanks again!

Hi Gianluca,
This sounds very similar to the bug I was seeing in XP. See:
https://www.osronline.com/showthread.cfm?link=146643
and
http://www.osronline.com/showThread.cfm?link=152900
If it is the same Windows bug that’s causing your problem, Microsoft are
currently working on a fix, but it’s taking them a very long time. Their
first attempt actually broke more than it fixed.
I’ll post to the group when I have more information.
Cheers,
Stuart

Same exact problem.
It would be great if you can keep me updated on it (even on my personal
e-mail).
Did you open a PSS with them?
Have a nice day

Yes, I submitted a support request back in January. Microsoft have been
working on it, but I think bugs in XP are very low on their priority list
just now.
I’ll keep you informed,

Do you know if the bug affects Vista/win7 as well?
