USB doesn't work after installing Parallels 7

[Luca Cirillo]

After the installation of Parallels 7, two of three USB devices of my MacBook Pro stopped.
I've uninstalled Parallels 7 and the USB restarted.
I've installed again Parallels 7 and the USB stopped again.
With Parallels 6, USB worked fine.
Thanks

Do I understand correctly that you are connecting USB devices to Mac OS X host?

Devices don't work even if no one VM running but PD7 installed, don't it?

Could you please post Problem Report ID? (http://kb.parallels.com/en/9058)

Dear Alev,
Yes, for both questions.
I've already open a ticket: 1210531
Thanks again

Dear Alev,
I've to add another issue: also the sound device is not working.
Also in this case, if I uninstall the PD7, the sound works again.
For your reference, I've attached the sound property screen shot.
Thanks

After installing the last revision 693916 of Tue, 13 Sep 2011 (build 7.0.14922) the issue has been solved.
Thanks Parallels and all engineers that followed the issue.

I've the same issue. After installing Lion my USB devices weren't recognized. I bought the update to Parallels 6 and Everything worked out fine. Because I've bought P6 I also get the update to P7 for free. Now I installed P7 the USB devices have the same problem. This problem can't be difficult to solve. They did it before.
Is there a possibility to downgrade to P6. My plotter and hardware key doesn't work now and I have some work to do.

Is there anyone who knows to solve this issue?

Also with the latest version (693916 of Tue, 13 Sep 2011 (build 7.0.14922)) I still have this problem
