Re: USB Drive not recognized - Driving me crazy!!!

Hello GTS,

Your question asking if anyone has tried the HotFix in the KB892050 article
I can tell you that I did obtain this HotFix from MS and it DID NOT help one
bit to solve the problem. MS does not furnish any instructions with this
HotFix, just two self-extracting Zip files. One of the self-extracting Zip
files (WindowsXP-KB892050-v3-x86-ENU.exe) actually performs registry changes
and (must) provide the two files (1) Usbehci.sys and (2) Updspapi.dll to the
Windows XP system (at least I found both of these files in my Windows folder
with the exact date and time stamp as specified in the 892050 article.

With regards to the second self-extracting file
(WindowsXP-KB892050-v3-x86-Symbols-ENU.exe)nothing quite so dramatic
happened. It just asks you in which folder you want the "unzipped" files to
be placed. No explanation was provided so I just specified a sub folder
underneath the folder containing the two self-extracting files. When this
self-extracting file is executed it creates a folder (in the location you
specified) called "Symbols" containing another sub-folder called "sp2fe"
containing another sub-folder called "retail" containing the last sub-folder
called "sys". The ONLY files in this chain is in the "sys" folder which
contains a file called "usbehci.pdb" , identified as a Palm Database File.

The confusing part of this entire HotFix is that there are no instructions
as to which of the two self-extracting files should be executed FIRST and in
which folder the second self-extracting file
(WindowsXP-KB892050-v3-x86-Symbols-ENU.exe) should be "unzipped" to.

As I mentioned, I installed this HotFix and then tried to install my Canon
Pixma MP530 printer via the USB 2.0 port on my PCI to USB Enhanced Controller
Card. The results were as before .... the device (printer) was not
recognized. I don't know, perhaps I have to uninstall the USB 2.0 controller
card and re-install it again before trying for the last time.

Considering ALL of the people having problems with this USB 2.0 - WinXP SP2
incompatibility, I'm simply amazed why Microsoft is not taking this more
seriously and providing a fully regression tested fix for this problem. In
the article KB892050 MS themselves listed the CAUSE of this problem as :
"This problem occurs because the Microsoft USB 2.0 driver causes an Enhanced
Host Controller Interface (EHCI) specification violation". Well that's real
great considering that the article was dated July 24, 2006. In other words,
MS considers this problem trivial and would rather spend their time fine
tuning VISTA so everyone having USB 2.0 problems can go out and buy the new
Vista O/S to get their USB devices working properly. Good business plan,
right ???

If anyone out there has any tips regarding the installation of the 892050
HotFix I'd be very grateful for your feedback. Thanks.

This continuing irritating problem of unexplained non-recognition problems

many of us.

I can only sympathize with your problem but I'm afraid I can offer no
concrete suggestions
that would help you although later on I'll list some troubleshooting tips
that we've been broadcasting re this issue.

The experience we've had with a variety of USB 2.0 devices, particularly
jump (flash, pen, thumb, etc.) drives parallels yours. And we know that

I wish you good luck.

Excellent Post!

In addition to the 10 suggestions you gave, I have also found with respect
to USB connected hard drives that if you put a different hard drive in the
same USB enclosure, Windows will often recognize it. Then if you stop that
drive and put the problem one back, it works normally.

At this point, I believe that the problem is in Windows, and not in the USB
spec. nor (usually) the hardware. Some of these problems seem to date to
SP2 which included several "fixes" for USB issues, though they do seem to
have gotten worse recently. I'm analyzing the registry changes that take
place as USB devices are enumerated and installed to see if there might be
some possibility of fixing things there (or at least forcing Windows to
re-enumerate unrecognized devices), though the key is probably bugs in the
Windows USB drivers.

Has anyone tried the hot fix in the following kb article?

A USB device that is connected to a USB 2.0 hub is not detected in Windows
XP Service Pack 2, Windows Server 2003 Service Pack 1, or Windows Server
2003 x64 versions
