Recently picked up a new camera and want to shoot tethered via the supplied usb cable. For some reason, my MBA will recognize the device connected when looking into the system information, but won't actually recognize the camera. So basically, I can't pull images off unless it's through a card reader and tethered capture is beyond question. Any insight on how to fix this? *Note: I've got another thread trying to trouble shoot power issues with my medium format digital back not drawing enough power via the FW800 to Thunderbolt cable. Could this be part of that power issue/MBA not outputting enough power to these devices via the BUS?
