Update December 17th 2015 : DisplayLink 2.5 driver for Mac is now available (stable version). It makes sure everything works on OS X 10.11 El Capitan though I’m still seeing one screen that won’t reach its full resolution.
Update August 26th 2015 : DisplayLink 2.4 driver for Mac is now available (stable version). Haven’t tried it myself yet but claims that many of the issues from the beta have been resolved or have workarounds.
Update June 29th 2015 : A new DisplayLink 2.4 BETA2 driver for Mac is available (released June 3rd 2015). It claims that “includes workarounds for some of the most severe defects in OS X 10.9 and 10.10” and links this article with known issues.
Update December 12th 2014 : A new DisplayLink 2.3 BETA driver for Mac is available (released October 10th 2014). It’s only a beta but it makes a HUGE difference in terms of performance on Mac OSX 10.10 Yosemite. If switching windows has been clunky and if your system has been overall slower than on Mavericks, then I highly recommend you give this patch a try.
Update June 17th 2014 : There’s a new DisplayLink 2.2 driver for Mac available (released June 10th).
I use a DisplayLink system to hook up a 3rd monitor to my laptop via USB. When Mavericks was released, the whole system broke but a beta driver was released (version 2.0) which seems to bring back the extra display even if very quirky. Then, version 2.1 was released but introduced a screen resolution problem.
