Hi there, As I was browsing the net other day and my Netgear Adapter stopped
working and it gave me an error of usb device not recognized. I called my
service provider and they tried all they could. Reinstalled driver etc. Now
my printer is not recognized. All my ports are not working now. I have
uninstalled and rebooted and they work for a few seconds then I get the error
message again. This has happened to me before and i cant remember how i fixed
it. Its driving me insane. Can someone please help me??

Does any USB device work?

You may have to remove all USB controllers, root hubs and ports in
Device Manager. After XP's next reboot, it should reset the USB
controllers and should re-install the correct drivers.

If this does not work, then you may have suffered a physical problem
with the USB controllers and you may never get these back. If they
are based off the motherboard, you can also add a separate PCI USB
controller.

Thank you for your advice. Yes none of them are working. I tried to put a
flash drive on at the front and that came up with the same error message.

Does this PCI USB CONTROLLER go inside of outside of computer? and how do
you know if they are based off the MotherBoard? Hope this is easy to answer
for you and easy for me to follow.

Kind Regards

Thank

If you have a laptop computer, ignore the following :)

A desktop computer has PCI slots.

http://en.wikipedia.org/wiki/Peripheral_Component_Interconnect

Some of the older computers, would have five PCI slots perhaps.
There is a picture showing that here. The faceplate of an add-in
card, would end up on the left hand side of this picture. Some
smaller computers, might only have room for two or three of
these slots, and some of the slots may already be occupied with
things like TV tuners or other cards. You want to start, by
looking inside the computer, for a spare slot like this.

http://upload.wikimedia.org/wikipedia/commons/c/ca/Pci-slots.jpg

The white thing on the end, is a "key", and it allows only
compatible cards to fit. This particular key marks the
motherboard as providing 5V to the card. Another key
(not shown in that picture, but nearer the other end of
the slot) would mark the motherboard type as 3.3V. Universal
PCI cards would work with either kind of slot. For your USB
card, this would not normally be a problem, or anything to worry
about. (As long as the card slides into the slot without binding
or mechanical issues, then you know you're doing it right. If the
card doesn't fit, come back and ask questions. Since computers
have three or more different kinds of slots now, not all the slots
are PCI, and a PCI card wouldn't fit in them.)

This Syba USB2.0 PCI card, would be an example of a card you can
plug into a PCI slot, to add five USB ports. Four ports are on the
faceplate of the card (on the left). When the card is plugged into
your computer, the ports show up on the outside of the computer, in
the I/O area on the back of the computer. So you'd gain four visible
new ports on the back.

http://c1.neweggimages.com/NeweggImage/productimage/15-124-008-07.jpg

SYBA PCI USB 2.0 4+1 port controller card Model SD-V2-5U - Retail $10
(The body of the card is kinda low profile, and other cards may be full
height, and yet be identical in function. Snipping away the excess
materials, reduces the cost of making the printed circuit board. Since
the purchase price is $10, every penny counts.)

http://www.newegg.com/Product/Product.aspx?Item=N82E16815124008

There is one internal port, and those are sometimes used to wire up
a tray mounted 9-in-1 card reader or similar toys. They can even be
used for a tray mounted USB hub (so you can get some ports on the front
of the computer). For example, this product would install in a hard
drive tray in the front of the computer, and a cable from this box,
connects to that fifth port on the PCI card. This would give you four
ports on the front of the computer, and they would be hosted by the
USB PCI card. Using this plus the PCI card, gives a total of eight
ports, four on the front (with this box) and four on the back (via
the PCI card faceplate connectors). On the back of this particular
box, is room to connect a four pin disk drive power connector (to
provide power to the hub), as well as a USB connector for the
provided (silvery) cable. The black cable on the right would not be
used (more likely useful when the box is used with a laptop).

http://www.newegg.com/Product/Product.aspx?Item=N82E16817801001

Notice there are two slots cut in the edge of the PCI USB card. The left hand
slot says "3.3V capable", and the right hand one says "5V capable". That
particular Syba USB card then, is a universal card. and would work in
any desktop PCI slot (5V or 3.3V).

A screw or fastener, positioned in the "dimple" at the top of the
faceplate, helps hold the card in place. Basically, you open the side
of the computer, locate a vacant PCI slot, remove a metal "blank" covering
the PCI slot hole, plug in the PCI card, install a screw or other kind of
fastener (whatever style the computer case uses) into the top of the
faceplate, and then the card should be mechanically secure. Put the
cover back on the computer and you're done. All work inside the computer,
should be done with the computer unplugged, and if you do your work that
way, the new hardware will not be placed in any danger by left-over
power in the slot.

When the computer is next booted, the New Hardware wizard is going to
notice the card needs drivers, but the USB2 driver already comes with
WinXP SP1 or any later Service Pack level. So the card should begin
to work without any additional work on your part. Now, plug in a
"test device", something unsophisticated (like a spare USB keyboard or
USB mouse perhaps), and see if the keyboard can type letters or the
mouse can cause the cursor to move around the screen. That tells
you that at least some basic level of driver support is working.

For more complicated devices (your MP3 player), follow the advice
provided in the MP3 player user manual. It will tell you whether a
driver should be installed before plugging the device in, or
after the device is plugged in.

This picture shows your new USB2 PCI card, as viewed from the
back of the computer. This person has installed their PCI USB
card, next to a video card (blue VGA connector). The single
internal USB connector, inside the computer, is not accessible
from the back, and is intended for internal wiring purposes.

http://www.coolcomputertoys.com/usb_pci_host/usb2_pci_host_card_installed.jpg

In this picture, you can see a couple PCI cards, with a screw
installed on the faceplate, so these cards are fitted and
secure and ready to use. The gold contacts on the edge of the
card, are fully inserted into the PCI slot, so hardly any gold
can be seen in the slot area. All this user has to do, is put the side
cover back on the computer and reconnect the power cord.

Thank you Paul. You have certainly put alot of effort in to type all that for
me. Thankyou so much. Very much appreciated. I will read it again so it
sinks in! lol

Cheers,

This seems pervasive, reading the USB comments. My USB ports (3 of them) no
longer recognize the printer, so I will try to remove all hubs etc and see if
the reset helps. I sent the computer in for repair, but it's still the same
problem.

When mentioning a problem like this, it helps to include the make and
model number of computer. Or, if you built the computer from parts,
the make and model number of the motherboard.

There is one Intel chip, for example, that can fail internally,
and none of the USB ports will work any more. In some cases,
the chip ends up with a burn mark on top, and the computer
won't boot any more. But in less severe cases, none of the USB
ports work any more, for any device plugged in.

If you have another USB device handy, use it to test the port. I
have a USB flash stick with a light emitting diode on it, which
is convenient for port testing. You can also use a USB mouse
and plug that into the port, to test it. My little portable
laptop mouse has a red LED in it, so again, can be used to
test for power, and for a functional response.

At the software level, ou can reset the USB stack, and have
the hardware re-enumerated again. This page covers doing it manually.

http://www.usbman.com/Guides/Cleanup Device Manager Safe Mode.htm

And this one uses devcon to do the work.

See RenewUSB.bat. "Warning: May cripple your OS, use entirely at
your own risk, and only after making a full backup."

http://www.robvanderwoude.com/devcon.php

Both procedures are complicated, and potentially error prone.
It is too bad Microsoft doesn't make a "repair tool" to set
it right. (It is times like this, I appreciate the PS/2 keyboard
on my computer. It would probably continue to run, while I was
fooling around with my USB stack.)

More USB tricks, are covered here.

http://www.uwe-sieber.de/usbtrouble_e.html

You can also test a computer, by booting another OS and testing
the USB port there. I use a Knoppix CD from Knopper.net for a quick
check. Everyone has their own favorite ways. Testing with another
OS, is to distinguish between a software problem with WinXP USB,
or an actual hardware problem. And with a USB printer, you have
that wonderful, crufty printer software to consider as a
culprit. That is why having some other, simpler USB devices
to test with, is nice.

Lots to try - thx for the materials. I have a Lenovo / IBM Thinkpad, T61.
The USBs all work for the iPod. Lenovo just replaced the planar, but the
problem persists. Spoke to the printer folks, had bought a new USB cable
before sending the laptop for service. I reset all the USB root hubs by
deleting them and rebooting. The USB says "found new hardware when I turn on
the printer, but then I get the error. When the printer was originally set
up 2 yrs ago, it did a plug and play. Just stopped being recognized 2 weeks
ago. Also, if the cable is unplugged and I go to plug it in, the machine
freezes until the cable is unplugged.

Did the printer software get reinstalled, somewhere along the way ?

I'd try

1) Uninstall printer software. Make sure you still have a copy of the
installer, or that the CD that came with the printer is still readable.
If you don't have any software to install, then removing the software
would be a step backwards.

2) Reset the USB stack, with printer disconnected.

3) After reboot and basic USB entries are healthy in Device Manager,
reinstall printer software. Only plug the printer in, when the
software says it is safe. Some USB devices need the software
first, before hardware is plugged in.

4) Does the printer show up now ?

You could try testing the computer with an alternate OS. The purpose
of that, is to see if another OS freezes when the printer is plugged in.
If identical behavior was obtained, then it could be a hardware problem
of some sort (like maybe at the printer end, since your planar has been
replaced).

I use a Knoppix CD (Linux LiveCD), which doesn't install any software
on the computer. It runs right from the CD. Some of the older versions,
have nice colorful text messages on the screen during boot. You can
watch them, to see how happy the OS is with the hardware. Once the
OS is running, programs like "lspci", "lsusb", and "dmesg" give info
about detected hardware. They can be run from a terminal window.
I have no idea how Linux deals with printers, and how easy it is to
actually print a test page from Linux. But that is the basic approach
I'd use.

The table at the bottom of this page, shows releases. 5.3.1 is probably
the best compromise version, in terms of being user friendly and functional.
But it only comes in a DVD version. That would leave 5.1.1 as an accessible
version, since it is only a 700MB download in ISO9660 format. The latest
versions have a desktop, that looks less like Windows, so may initially
be a bit daunting to use. The latest version also doesn't do as nice a
job on the startup text messages. So I guess that leaves 5.1.1.

Not sure if this would help but I did read, year ago, the the iPod can
take control of the USB port and may block the other devices.

Also, check here: http://www.uwe-sieber.de/usbtrouble_e.html

Uwe has given several sections with possible methods to fix this. Be
careful!!
