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

[MrT0ad]

Hi beautiful people:

I have just upgraded an iMac Mid 2010 running OS X 10.7 Server from Parallels 8 to 9.

The Win7 x86 Boot Camp partition was mounting fine on Parallels 8 and everything was functional, but since the upgrade the "Human Interface Devices" category is constantly dropping one of the devices, then rediscovering it, only to drop it again straight away.

The "offending" device IDs seems to be USB\VID_203A&PID_FFFB which a quick Google returns as pertaining the device "Virtual Keyboard".

I have unplugged every external USB device (including the keyboard) but it makes no difference... the infinite loop carries on.

Any suggestions beyond downgrading?

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?

The issue seems to be with upgraded VM's. Apparently new VM's don't have this problem but seems like it should have been caught in testing.

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.
