major disconnect issue with Canons on 10.7.4
Our techs are having a lot of issues with our Canon cameras disconnecting on set, though i'm having a hard time reproducing the problem when the systems are back at our office.
Essentially the issue is when using Capture One or EOS Utility the camera will connect ok, but after the first frame is shot the progress bar on either program will freeze. Capture One will report "pending..." but nothing will happen. They're having to dump the battery from the camera to clear the problem.
We are using CaptureOne 6.4.2 with 2 different Canon 5Dmk2s on an iMac 27" running Lion 10.7.4. We've been using the same exact system for many months but the disconnect problem has only been plaguing us for the past month or so. Any ideas about what could be causing the problems?

The ports on the iMacs have been a bit sketchy for power output. The cameras don't need any power from the USB to run, but the signal needs it to be carried properly. Try a powered usb hub and you will likely see consistency improve. 0 -
Well we have been using those USB repeaters along with the tethers. It seems like I would have still seen that when I tested them out beforehand. They're also using an APC battery backup on the iMac and they're shooting in studio so the power should be good, if that matters at all. 0 -

Well you were basically right I think. Just discovered they actually weren't using the USB repeaters when they had the disconnect issues. When we plugged those up the connection problems were definitely mitigated. That led me to test with a brand new USB tether (same kind and length, just unused) and it worked fine without even needing the USB repeater. Not sure how that differs from a powered USB hub but at least theres no separate power cable to have to run. In this case I guess the culprits were bad tethers but that the repeater helps. Thanks for helping!0 -
Ultimately its about strength of signal and anything that helps create stronger signal (in this case better cables) will help.. The repeater is a good trick to keep in your back pocket if you run into problems suddenly or find some kits less reliable than others.
Glad you were able to get it working better!0
