I have an old digital camera I use for ebay and it has always worked on my Vista LT. Lateley been getting the message "USB Device Not Recognised" when plugging it in. When I go to device manager it shows up as an unknown device? It also showed up the same on my other identical laptop which never had a problem with the camera before.

The camera is small digital old Olympus but that is not the issue as it already worked before. Besides, I uninstalled the camera/unknown device just now and did a total power shutdown, battery out pressing power button for 60 secs. I then rebooted without the device connected on battery alone.

As soon as I plugged it in it began installing the software for the camera but then the "USB device not recognised" came back and the device doesnít show up in the 'My Computer' Drives section. Donít tell me this is not a Vista issue.

HP Laptop running Windows Vista Home Edition

A mate of mine who does programming said that there usually is sometimes power issues with the different ports and they get confused when different applications are plugged in - I need vista answers not a camera faults section.

So that means you won't like my initial answer.

It also showed up the same on my other identical laptop which never had a problem with the camera before.

This tells me that it is a camera issue and not a OS issue since you are telling us it fails on your other laptop. This pretty much identified the problem.

With that said, have you tried other USB ports?
Have you gone into device manager and uninstalled yhe USB ports, shut down the laptop and then re-started so the OS would re-install them?

Yes, am way ahead of you and have tried all the fixes you recommend. It is a Vista issue because it is common with Vista on Google. Besides, my wifes camera got the same response on my laptop and then I uninstalled it and it worked. I then plugged my own camera back in for fun and it worked. Then the next day it didnt work. Its random which sounds pretty much like vista getting itself confused to me.

Deleted all the usb hub list as a microsoft site suggested and rebooted but still problem exists.



So if this problem has been around on Google for years, why isnt there a fix for it or why hasn't anyone got answers for it?

Personally, instead of connecting the camera to the computer, I simply insert the camera's flash card into a USB Card Reader. They're cheap and you don't wear down your camera batteries.

For example:

Rosewill RSD-CR106 Black USB 2.0 External Single slot SD / MMC Card Reader - $5.99 with free shipping

Am in agreeance with one of the posters on the microsoft site who said, "It baffles me that THOUSANDS of people have this issue or some variation of it, and NO ONE at Microsoft or anywhere else for that matter offers a real solution"?

Not only that but it has been known for many years and still no simple answers which their should be....?

Someone on another site said this;
"try this. go to C: then windows, then the folder nameed inf. backup these 2 files..
usbstor.inf and usbstor.pnf copy them to a folder you can access later.


download these 2 files. and replace copy them into c windows inf folder.

reboot pc. this will reset corrupted files.

Attached File(s)
usbfix.zip ( 12.09K ) Number of downloads: 2"


Did it and it worked until I removed my camera and replaced it - same ol message.

Two questions:
  • Do you have a USB port?

  • What type of flash card does your camera use, (SD, MMC, etc.)?
