Parallels 9 "Human Interface Devices" constant device disconnect/rediscovery

Today's update fixes all the USB issues for me on both Snow Leopard and Mavericks hosts.

 

For me too on Mountain Lion host (MacBook Pro late 2011).
I'm glad I didn't have to downgrade to PD8

 

How to stop that mouse pointer to stick at window edges when the optimize for games is on?

 

I am having the problem on a newly created VM.

 

I was watching this thread - and some of the others - since I got the "upgrade" email. I waited until I saw someone's post that the latest update solved the USB/mouse issue. I purchased and did the install - existing VM with Windows 8 running OSX 10.8.4 - and so far no issues at all. Everything boots and works properly - including Apple Bluetooth Keyboard and mouse and a Logitech USB mouse and Epson USB printer. (BTW - the mouse also works fine in the few games I have tried. Both native Windows 8 games that run in the Start Screen by Origin - Dead Space 3.)
Have not checked after the install (about 3 days ago) to see if there is a further update that someone in another thread was complaining about.
