Default MBP 8,2 HIS II DL-195 adapter not working

This adapter originally worked fine on OSX 10.7.5, then after updating to 10.8.0 it stopped working in July 2012.

I have since reformatted with a fresh 10.8.2 and tried the new 2.0 alpha driver and it looks like the exact same errors.

2/25/13 2:22:43.000 PM kernel[0]: USBF: 6660. 60 [0xffffff8027a87800] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 2 of Hub at 0xfd100000)
2/25/13 2:22:43.000 PM kernel[0]: USBF: 6660.802 [0xffffff8027a87800] The IOUSBFamily has successfully enumerated the device.

FYI This adapter works fine with Windows.

It is now working!

The issue I believe is something to do with Thunderbolt and USB.

According to this thread which were seeing the exact same types of messages in the log as I was seeing:

https://discussions.apple.com/thread...art=0&tstart=0

It turns out that removing the Thunderbolt display and then plugging the HIS II into the USB port did the trick.

I then plugged in the Thunderbolt Displayport and it also came on.

So I am writing this viewing all 3 displays!

FYI I always had the Thunderbolt Displayport plugged in never occurred to me to unplug it.

So this issue has come back and what originally worked above no longer works.

Third monitor no longer comes on and I keep seeing the same messages in log.

The only thing I can think of at this point is using a powered USB hub.

Ideas?

Are you using Beta 1 build we've recently released?
Please use it and capture fresh logs if the problem remains.

Thanks,
Michal
