Got a new(used) 7D and having an issue with tethering. Works fine at first but if I turn the camera on or off, or unplug the usb during a session, tethering won't alway resume when I turn back on or plug back in. It's inconsistent, the camera is always recognized by lightroom but doesn't always transfer the photos when I resume shooting after plugging the USB back in. Firmware is up to date and so is lightroom.
This was never an issue with my 50d. I've checked it with different cables and USB ports.
