USB not working for camera

[dsarchs]

I recently built a new system and everything had been working fine but recently it won't recognize my camera/usb when it's connected.

It had worked originally but now -- although it beeps when plugging/unpluggin the usb cable -- nothing shows up on the computer at all. My wife mentioned that she had canceled out of something once when she plugged it in and it wouldn't work after that, but I can't figure out what it was she would have canceled or how to reset it.

Any ideas?

System information:

Windows 7 pro
i5-2500k
HD 6950
1tb spinpoint f3
8gb 1333 ram

The camera is a cannon powershot sx-130 is, if that matters.

This is the same for every usb port on the computer. Other devices (ipod, for example) are able to use the same usb ports with no problems and the camera works just fine on other computers.

As a side issue, can you plug usb 2.0 devices into a 3.0 port?

Now I feel stupid :/ I was not paying attention to which usb cord I was using for the camera. I was plugging the camera in using my wireless headset charging cord. Lucky that I did not blow some thing up!

I keep forgetting Occam's Razor

physoc - thank you. Mine has not been working for years. No more trundling along to the other pc and back with a USB stick.

Just to make it a bit easier. You can go to "services" directly by typing it into the start bar box and then find "WUDFSVC (Windows Driver Foundation - User-mode Driver Framework)" and then setting it to "automatic". I then had to manually click on the entry for my camera in device manager and update the drivers, it then popped up via autoplay.

Mine is an Canon Ixus 850IS.

This worked for my 30D with Win7 64b computer:
Change the setting in menu > the last icon > communication > change from PC to print/ptp and you will be able to communicate again with the camera.

+1 to 24jj -

That worked like a champ to get my 300D talking to the Win7 machine.
No new drivers required, no rebuiding the hard drive, no kissing your sister.

I just looked up this question to find an answer - don't know if you ever figured it out, but my easy solution for myself was: Plug in the usb cord to the computer first. Next, plug the other end into the camera. NOW it recognizes the camera.

As I said, I've downloaded the software from canon (same as what is on the cd that came with the camera) but it's just viewing software and the computer (including the viewer) cannot find the camera.

I'm thinking that the problem is the MTP USB device -- that is what's listed under the camera properties in device driver. I get an access denied error when I try to update the drivers though. Several reboots with new change to that.

Cannon's website says it doesn't need a driver to work, which is why I think it must be a generic driver (as above) that's missing/has problems. I'm a little surprised that every other usb device works just fine, though.

One other thing -- I'm using Comodo firewall; is there a way that that could have accidentally been set to block the camera and if so how would I unblock it?

Cannon Rebel, and Gopro Hero 3 +...worked before don't recognize now..plug in, here sound..no pop-up..Windows sucks. But unfortunately they have us by the short and curly's...Brought my computer in to a computer repair shop..After being told the problem was fixed, No dice..Bought Windows 8 ( very F*&*ing reluctantly) now works fine. I have been following this thread for awhile and I have tried everything posted..That's the thing about computer guys..They use Google to fix the problem just like us. Very hard to find someone who REALLY knows all the ins and outs of the software. Like I said, I bought Windows 8 and everything works fine now..Good luck...Probably not going to find your answer here

Not and answer, but I'm having the same problem with my Canon G7. The first time I plugged ot in the 'device driver' apparently loaded OK. I download files....Later when I plugged the camera in again....noithing! Eventually I restored the PC from a backup to prior to the original install, and then OK. The driver installed, I download files. Then later....nothing! It seems that something is killing the camera drivers at some point.
I checked the firewall and I have the Canon bits OK'd, so I'm unclear what's going on.
My other camera (Nikon) also has stopped linking.
Both work fine on the laptop....?

Update. I can manually install MTP USB (in device manager) and it all works fine. However if I reboot the problem comes back. I beleive that the system is not initiallising MTP USB at boot-time. Maybe in the SERVICES there is something that's disabled? Anyone got any suggestions?

UPDATE: SOLVED!
The problem was with a SERVICES entry; WUDFSVC (Windows Driver Foundation - User-mode Driver Framework) which should be running all the time and set as Automatic start....it wasn't! In the event I had to modify the registry entries for WUDFSVC (I think I had three) and find the START mode entry and modify them to (2) (automatic). They had got set to (3) (manual). Since doing this the system is working fine again.

Came across this thread while searching for an answer to this problem. Got my Canon EOS Rebel XT back from being cleaned and wouldn't work when I connected/usb to my Laptop (though it had before). Also closed a box after choosing what I thought was the right answer. Went to Canon's site and they don't have drivers for Windows 7 (64x) OS so went to Microsoft and typed "make my canon camera work in Windows 7 (64x)" into search. This is what they had to say:

- - - - - - - - - -

(Q: Windows 7 will not recognize my Canon Rebel xt camera, but easily accepts the Canon PowerShot Point and shoot as well as the Fuji Film Fine Pix camera. The memory disk for the xt is a Compact Flash Disk while the others use the smaller SD disk. So, without having to use a card reader, is there a work around?)

A: Change the setting in menu > the last icon > communication > change from PC to print/ptp and you will be able to communicate again with the camera

- - - - - - - - - -

Changed the setting on my camera, connected through usb and it loaded the correct driver and asked how to offload photos. Made my selection and nothing happened so I turned the camera off and on again... my photos are downloading right now...

Hope this can help someone out there. Noelle

CANON stopped supporting the REBEL-XT years ago. The old driver (the last they produced for the XT) will not work correctly but you can get it to work by uninstalling the driver from device manger and then reinstalling the driver. Then the window explorer file manager will pop up showing the device. (XT must be in "Print/PTP" mode).

After each drive reinstall when the computer is powered off and powered up again Windows will not communicate with the XT again so each time you have to uninstall the driver with the XT on and plugged in, then turn the XT when plugged in off and on again and Windows will see it, give a fresh driver install now seeing the XT again.

It is a real pain each time you power up your computer and want to use your CANON REBEL--XT to uninstall the driver and then reinstall the driver each time but it works.
