USB cannot tether to DSLR Camera
I am a professional commercial photographer, and I typically shoot directly to my computer, either a laptop, or an imac.
I purchased a 21.5in mid 2011 imac (OSX 10.7.5) a few years back and the usb port never tethered to the camera at all.
I have tested the camera and the USB cord on other computers, and they are not the problem.
My initial solution was to purchase a powered USB hub, and that solution worked well until about a month ago. At first the camera would disconnect from the software and I would have to unplug the USB and turn off the camera. Then plug in the USB and power the camera back up. But it's getting less and less reliable. Disconnecting the camera every 3 frames or so.
All the USB ports on the imac works. I use harddrives, flash card readers, etc. All works fine.
I have since purchased a 27in late 2012 imac, and can connect the same camera and cord and software combo directly to the USB 3 port, with perfect success.
But I would still like to be able to fix the old computer for a backup if needed.
Can anyone guess at what the issue might be? and provide a solution I can try. Thanks so much!
