Hi, I normally use a Canon 1Ds Mk II but as this cannot tether to a windows based machine via USB (needs firewire) I purchased a Canon 600D as a backup and to try out tethered photography in the field with a small laptop running windows. Also DL'd Lightroom 3 to test out. Now I have updated LR3 to 3.5 and the firmware on the 600D camera I updated to the latest. When I launch LR all goes well but as soon as I connect the camera and click on tethered under the file menu I get the BUSY showing in the camera viewfinder, I uninstalled LR and put on Canons software and that worked fine but I want to use LR. Why am I getting the BUSY signal? I have also tried connecting the camera in other USB ports on the laptop.
Thanks for any help.
