There is an error in the V0.3.4 desktop versions (Linux, OSX, Windows) that prevents the USB connection to work.
Download and unpack the V0.3.4_fix archive into the V0.3.4 folder and overwrite the qDslrDashboard executable.
In case of the OSX redownload it again.
qDslrDashboard V0.3.4 is now available with the following changes
- added BULB capture for Sony cameras that support it (needs the latest ‘Smart remote‘ on camera)
- added custom bracketing for Sony cameras (A and M mode)
- added Lumix GH4 (and probably other Lumix models that support PTP mode) USB connection (their PTP implementation is very basic, capture, change shutter/aperture/iso, browse/download images)
- other fixes reported by users
I wish you all Merry Christmas and a Happy New Year.
