O.k. just f.y.i. i am not a complete computer guru and have only some knowledge of computer tech. I have reviewed eons of posts and have come to no conclusion for my usb problems.

That being said here is my dilemma:

I have a Sandisk cruzer 1gb that doesn't show up in device manager, disk management, or My Computer. I have attempted to update drivers from the devices website, but its says i already have the drivers necessary. I know that it my usb port is "talking" in a sense to the flash drive because when i plug in the drive i hear the ba-ding tone that tells me something new was connected. This flash drive works on other people's computers as i have tested it on three others. I can plug other reliable USB devices into my USB port(s) and it works fine. I have tried the flash drive on all the ports on my computer, and to my dismay none of them recognize it. I have no idea how to fix it!

I have 2 External USB 2.0 SAMSUNG LightScribe DVD+CD burners. One has been showing up in my device manager as an unknown device and it has worked plenty of times before. The device does not have a question mark or exclamation point over it in the device manager. When I have tried to update the drivers via Hardware Update Wizrad it tells me that it could not find any drivers better than the ones installed. I've had this problem before and it magically fixed itself after a month or so. The power saving feature has been disabled (the port doesn't shut down to save power). When I plug dvd burner #2 in it doesn't recognize the burner and instead of being a unkown device in device manager, it says, "USB storage adapter AT2 (TPP)" with a red "x" through it it says that the device is disabled and for some reason it won't let me enable it. Any ideas?

Sounds like your USB chip is going/gone.

A PCI card for USB capability works, http://www.newegg.com/Product/ProductList....me=%241+-+%2410

I would also try removing all drivers for the USB capability (using Device Manager) and a reboot of the system.

I'd also take a look at errors reflected in Event Viewer that might impact.

What kind of computer do you have laptop/desktop? Are your external devices (flash drive / DVD burners) connected to the comptuer via a hub?

if this is a Desktop, replace the motherboard. if it's a laptop, start pricing out a new(ish) laptop.

If you have a desktop machine and a spare PCI slot then you could buy a 5 Port USB 2.0 Card. Getting this would circumnavigate the onboard (mobo) chipset and should allow you to connect your devices.

Ok so i did a little poking around via registry editor and i managed to get my USB ports to recognize the sandisk drive :huh: , but now it says that the drivers are not installed :thumbsup: . The DVD drive is now showing up as an unknown device in device manager. is this a driver issue?

if so, is there a way i can re-instate the drivers for my devices? i have tried a few free-ware programs that try to help me detect the drivers i need, and those don't seem to be working. And in my searching Windows update i have only seen drivers for windows 98. Help?

you can run CCleaner and use the registry option, you'd have to make multiple passes till it reported no errors.
there is Driver Cleaner, used to be free, but that may work. if the ports are visible in device manager, I'd try forcing them to take updated drivers. that will mean going to the manufacturer of the unit (since there's been no word as to if this is a laptop or dekstop), the last resort would be to back up your data, and reformat and reload windows from scratch.

It would be nice to know what you mean by "poking around via registry editor" in the registry.Does that mean you eliminated registry entries?

Since the result of such seems to have been problems that you didn't have before...maybe you need to try to undo that.

As for devices which are reflected as "unknown", those typically are devices requiring drivers.

The easy way to address that is to remove drivers via Device Manager...reboot...allow XP to use native drivers...use the driver CD which came with your system to reinstall drivers...and use any driver disks which you might have for other components to install such.
