Odd issue with Digital Camera

Posted in Linux, ubuntu by microwavebiscuit on April 29, 2007

I’ve been having an issue with my digital camera and connecting it to my Ubuntu pc. Here’s what happens, I plug it in and then it prompts me to import the pictures, etc. After I do that there is also a “disk” on my desktop that represents my camera. When I’m ready to disconnect my camera, I right click on the disk and choose “eject”. So far so good, however the next time I connect my camera it won’t work. The only way I’ve found to solve it is with a reboot. So, it seems to me that somehow I’m not disconnecting it correctly or something. I’d like to resolve this – any thoughts?

Also – here’s some info that comes out of log check which I think relates to the camera:

    I think you can just reload the USB driver rather than rebooting. This is not ideal either I know, but a great hack for now.

    I think the module is uhci_hcd so the commands would be:
    sudo rmmod uhci_hcd; sudo modprobe uhci_hcd
