Hi, I have an HP 620 Photosmart digital camera. It used to work fine, I could open pics in folders or image viewers. Then my tech buddy set up a network connection with another office computer to transfer/share files. Also my D-link router died and I replaced it with another. I ran some updates per the update manager. I haven't used the camera in a month so not certain of the precipitating event, all I know is that when I plug it in to the USB port, this computer doesn't recognize it any more. There's no prompt or recognition that the camera is there. The camera does say it's connected but the computer doesn't know it. No pics can be viewed or downloaded. Memory sticks do display so I know it's not the USB connectors. The camera works fine on my other computer, different version of Ubuntu. I was able to upload pics to ebay. So I know it's not a camera problem either. My friend spent all afternoon trying to trouble-shoot with no luck. He said he has never had any problem in the past with Ubuntu recognizing a digital camera, this is a first for him.
