Odd issue with Digital Camera
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
