Mountain Lion upgrade, display no longer working

[timmedley]

I recently upgraded to ML and now my DisplayLink connected HP LCD is no longer working on my 2009 24" iMac.

I have uninstalled/reinstalled the latest 1.8 driver, changed USB port the adpter is connected to, run applejack, repaired permissions with Disk Utility and rebooted several times during each of these.

System Info does see my adapter connected to the Mac.

Hoping someone can make sense of the attached Info/Logs.

thank you,
