FYI, to obtain a hotfix from MS you must call product support. The
number can be found on their site. hotfixes are provided free of
charge, but are not regression tested, so make sure your symptoms match
what is described in the KB article for the hotfix.

Thanks for the comments Floyd, I have the Microsoft-indicated SYS and DLL
files. These were just installed from .NET framework 2.0 and are the latest
versions except for the Hotfix versions mentioned by the Microsoft
Knowledgebase reference. I note that the exact same files are on my desktop
as on my laptop but the laptop won't accept the USB phone while the desktop
has no problem with it. THE USB ports seem to work ok, just certain items not
accepted. Most frustrating!
I also have occasional problems with other people's flashdisks on both
machines where the system wants to look for a driver then can't find one.
Seems like everyone has had this problem at one time or another. Guess I
stick with headphones on my laptop for a while!

vp,
Those *.sys should have come with the .NET program.
You could do a SEARCH or LOOK in your Windows>SYS directory to verifty that
you have these files.
The files should have been included in WindowsXP and others, but probably
not Win98 as there were no USB's back in them olden days of yore.
If you still have your original CD for your operating system you can do a
RESTORE from them.
If the USB's did work at one time, you could do a SYSTEM RESTORE to an
earlier date, say 3 months ago, not last week or month.
Good Luck, I know it's frustrating.

I am having a very similar problem installing a USB phone for a USB 2.0 port
to my Sony Vaio FS-742/w laptop wherein XP Home SP2 keeps asking for a new
driver to be installed but never finds one it is happy with although the
phone works on other machines running XP Home Sp2 without any additional
driver being installed. All my drivers appear to be up to date per Sony and
Windows Update
I have installed (re-installed actually) .NET Framework v2.0 but still am
having the same problem. Microsoft mentions the need for a hotfix for the
usbehci.sys and updspapi.dll files but isn't very clear as to where to get
these.
A very annoying little problem!
Any other suggestions would be appreciated.

I had the same problem and called my manufacturer. They were not aware there
was such a HUGE problem with these devices.
There is a software problem and mine was caused by Windows Update.
Goto WINDOWS DOWNLOADS
Select .NET Framework Versin 2.0 Redistributable Package (x86 - that was my
system - you select yours)
Download or Install.
This is a 25Meg program that fixes all sorts of other problems too (COM,
SERIAL, KEYBOARD, etc.)
It containes all sorts of driver fixes that are not included in your Windows
XP, 98, etc. Why Microsoft didn't include these in their Win Update is
beyond me.
My FLASH DRIVE was IMMEDIATELY RECOGNIZED and is still working GREAT.

I really hope someone out there can give me some substantive help with this.
I have just purchased a Dell 512mb Flash Drive and my system at home will not
recognize the device. I have also had the same problem with a SanDisk 512 mb
flash drive. Both of these drives have worked fine on numerous other
computers. My system is running Windows XP Pro with SP2 loaded. The USB Host
Controller drivers (Intel) have all been updated, uninstalled, reinstalled,
and updated again. I have checked everything I can think of in Device
Manager. I even went into BIOS out of desperation. Nothing I have tried works.
Another symptom I have noticed is that if I try to boot the machine with the
Flash Drive inserted, the machine will not boot and tells me it cannot find
the OS.
Please help, I've been everything from a software engineer to a network
administrator, to a programming teacherfor 17 years and I've never had a
computer problem that frustrated me this much. I've googled this to death and
it seems like i see the problem posted a lot, but no useful solutions.
HELP!!!!!
