Display identified properly, but no video and USB error in dl.log

Another excerpt from system.log yields:

Aug 6 21:17:57 alexander com.apple.launchd.peruser.0[560] (com.displaylink.useragent[616]): posix_spawn("/System/Library/Extensions/DisplayLinkDriver.kext/DisplayLinkAgent/DisplayLinkUserAgent", ...): No such file or directory

Unlike a person reporting a similar issue two years ago, however, I find that file properly placed and privileged inside the .kext container.

Could you please try to uninstall the 1.6 driver and install the 1.7b3 just for a test. Repair permission after uninstalling the 1.6 driver (it should be not necessary, but just to be sure everything is ok).
What happen if you change to another resolution available?
Could you please send debug information after installing the 1.7b3.
Thanks
