I have the same computer and had the same problem. I re-installed everything, returning the PC to new/out of the box condition. This didn't fix the problem. So, I decided it could only be a failure of the onboard USB controller.

I ordered a new USB 2.0 PCI Card (low profile size for the small case) from StarTech for $20 (ordered from Officedepot.com).

Installation instructions are vague, so, if you're running XP or Vista, there are one or two important things to do before placing the card in your machine.

First, go to the hardware manager and uninstall the modem, since you'll be removing this from the one and only PCI slot. Second, DO NOT remove the current USB controllers, rather DISABLE them (disable the top two lines on the USB tree list -- This will make the USB Hub and Unknown Devices below those disappear). This will allow XP or Vista to properly recognize the new StarTech card after install and install new USB controller drivers rather than trying to use the existing ones.

By the way, if you're running XP or Vista, you won't need to install the CD that came with the StarTech card.

So, this solved my problem. It's a $20 fix, but necessary. I hope this info helps.

Is it connected via USB port? Do you have other devices connected printer etc. May be an IRQ problem. Depending on what platform you are running XP, Vista, etc Normally resolved in Device Manager. Is the Cam powered externally? can be due to non or low power output on USB hence not discovered. M

Check to see if something else will work on the side port. It may not necessarily be a dead port. Just something you should know too; I used to work for Wal-Mart in the electronics department and they had to recall all their firefly flash drives because they had a tendancy to malfunction. Try using it on a different computer, it might just be a dead flash drive. I hope this helps your problem and I hope your flash drive didn't have anything too important on it :x

Windows Vista has compatibility issues with many webcams because the ACPI is different; need to know the make/model of your webcam.

Is the webcam USB? Try rebooting the computer with no other USB devices connected. If you're still having the problem try it through a separate mains powered hub. Webcams can often overload the USB ports on laptops.

Test print page error says printer is not on line. Paper advance works and power is on. Drive error says not enough information.


I suspect your printer port is dissabled in the bios , tripple check to make sure the printer port is enabled and let me know what happens. printerport IRQ = 7

if this is a USB printer , tripple check to see that your USB ports are enabled in the bios and have an IRQ assigned to them , namely IRQ 11 which is the default and you need not set it manualy.

Use the Primary USB ports , not the extended ones as they may be dissabled by accident or have faulty wireing.

let me know what happens.

Possible usb malfunction?


hi,
well xp is a better OS than 98 ( i think) ...
few things you should know that xp is pre-installed with lotsa drivers..but on the other hand 98 isn't .. so each time you put in a USB device you need to install the driver for that device( eg your camera, pen drive etc...) . this drivers would be there accompanied with your device.
hope it helps

Usb malfunciton


Open device manager. (Settings, Control Panel, System)
Expand system devices.
Open PCI Bus, then IRQ steering.
This should generally be enabled, but disable it if it isn't working for you.

When you restart the computer check the system bios (Usually "Press <del> to enter settings" to see whether you are allowing the operating system to control devices through Plug and Play. Either setting may work, but setting to Plug and Play Operating system is generally better with IRQ steering enabled. Try all combinations.

Although MS no longer supports Win98 you may find that Windows Updates still works. You should take whatever updates are available.
