Well, I reran the file transfer that I was running just before the last
crash. The drives have been rearranged on the USB chain. It went through
properly this time. Not really a scientific observation, but anecdotal.
We'll see if the system stabilizes after a few more days pass.

Crap, spoke too soon! Although that particular file transfer did go
through properly this time, but the system did have another BSOD later
in the day. This time it was a Stop 0xCD
PAGE_FAULT_BEYOND_END_OF_ALLOCATION. According to this Microsoft KB
about Windows Server 2003, but probably applicable to XP as well, it was
due to a delayed write error.

Error message when a Delayed Write Failure event is reported in Windows
Server 2003: "Stop 0x00000019 - BAD_POOL_HEADER" or "Stop 0xCD
PAGE_FAULT_BEYOND_END_OF_ALLOCATION"
"This problem occurs because a certain driver returns an empty device
name to the operating system when a Delayed Write Failure event is
reported."
http://support.microsoft.com/kb/925259

Now during this entire period, I've seen both the Stop 0x19
BAD_POOL_HEADER and now the Stop 0xCD messages at various times, as well
as other Stop messages.

Hmm. Not good.


Sounds good to me. Let us know. I have had to take USB ports out
of service in the past as well, but that was on an ASUS board
where they had insufficient cooling on the southbridge, and
it was not really a surprise to me that portst started giving
up after about 2 years. No more ASUS for me, they are more
expensive and their engineering sucks badly lately.

I don't know who's more to blame here, Asus or Nvidia. I've had it upto
here with both.

Yes, me too. My last Asus board (replacement for the badly cooled
one while it was in warranty replacement) died after 3 days form a
badly designed northbride cooler with too weak springs. The
replacement for that had thermal compound incompetently applied
over a not removed used phase-change pad. I have now replaced
their shoddy work completely with a 3rd party cooler and that
does work better and leads to acceptable temperatures, but I
think the time were Asus was a quality manufactuere are long over.

Most of Asus' AMD motherboards used to use Nvidia
chipsets. And most of the computer stores around here only sell Asus
motherboards for some reason, whether Intel or AMD.

Incidentially my Asus GeForce 8800 is now in warranty
repair for the 3rd time, also shoddy cooling and on
the last repair it cane back with a manually thorn off
capacitor. What also is really bad is that Asus takes something
like 4-8 weeks for a replacement.

For Mainboards, I have moved to Gigabyte for the moment. Better
cooled, because they use twice the copper plating thickness in
the power and ground layers and it is noticeable. Still not perfect,
but no worse than Asus and I can get amost 2 boards for the
price of one Asus board, so I now have my own spare here.

As to the damaged port, it would still support a mouse or the
like, but filetransfers resulted in device disconnects under
Linux, a bit like your situation. Incidentially, this problem
also affected the SATA port with the same number, I guess they
were arranged in SATA/USB pairs on the chip.

Is there any utility which will monitor USB disconnects? I don't
seem to see them in the Windows System logs.

I really don't know. If Windows USB is not completely FuBar,
then these should be in some log.

I'm hoping that the rearrangement of the USB's is really going to
actually work out here, and that this was just a fluke, like a last
goodbye punch to the face.

It's for reasons like that that I insist on motherboards with
integrated graphics these days. At least if your fancy discrete
graphics card goes dead, you can still continue to work on the
computer at some minimal level, even if you can't game. But as soon as
say integrated graphics, they think low-end value-priced motherboards,
and they don't make them with various features like SLI or Crossfire,
etc.

seem to see them in the Windows System logs.

I really don't know. If Windows USB is not completely FuBar,
then these should be in some log.

I have a simple USB-to-serial port converter cable that can bring my
whole system to standstill, on this system. It's like as if all of the
USB ports stop working sometimes when this cable is attached. Other
times it's just fine.
