Nicke
Hello!

I lose connection between C1 (DB 7.2) and my Phase One digital back(IQ160), first find C1 it and then drop it then find it again and drop it and so it goes on all the time.
I have a Mac Book Pro (Retina) late 2012 with(Software OS X 10.9.1) i try to connect with USB, i have try it on a nother computer and it works fine there.

Regards Nicklas

    How long of a cable are you using?

    Have you tried a powered hub?

    Are you running other USB devices at the same time?

    I have tried this http://support.apple.com/kb/ht4049

    IQ160: (this is the info from usb'n when P1án is plugged in to the computer, it looks like the P1 require 124 (mA) and the usb delivers 900 (mA), this is really strange 😲( )

    are you powering the back through the system bus or by battery?

    I would repeat the tests you have done running off of the back's battery if possible.

    Have you tried a clean install of Capture One?

    I´m powering the back with battery, fully charged.
    I just tested with a clean install but no changes

    Do you have a CF card in the back?

    Is there a new firmware that corresponds to use of the IQ160 in C1Pro 7.2?

    Does this machine connect and run the back reliably in C1Pro 7.1.6?

    If you go into "about this mac", is the computer seeing the back as USB 2 or USB 3? If USB 2, restart the back and see if it connects as USB 3.

    Please turn off the Charging Feature when tethered over your systems USB.
    It looks like your system doesn't like the power demand.
