Yes, that's all very embarrassing. From talking to ex-colleagues in the pub, they are actively working on it, but it all got stirred-in with MacOS support for the more recent USB3 Displaylink chip. Which is no excuse really -- everyone knows that most Mac people (unlike, say, Windows people) update their OS as soon as the new one comes out.

Yeah, according to whoever it is speaking officially on their forum they are getting on with rearchitecting their whole driver stack to support the USB3 devices. And they are doing that to the exclusion of work on the existing drivers. I get the impression that they are hoping, but don't know for certain, that it will also fix the other problems with the USB2 devices (though their spokesperson seemed to admit they don't know the cause of all the problems).

I feel for them, they clearly aren't being allowed to fix things properly due to someone further up the chain.
