I'm running: Parallels 4.03846 with Windows XP (Home Ed) on a Mac Pro, OS 10.5.8 This issue has been ongoing for several months. I also have an ongoing support Ticket #773283. Here's the situation, and it's quite random: After a restart of Parallels, or after resuming a saved state ... I'm unable to re-select my USB devices. * They do appear in the USB devices menu in the bottom right corner (Window View) with a lock next to them. * When I attempt to select them, they disappear from the list. (and do NOT get selected) It does NOT MATTER if I have the device(s) pre-assigned to the VirtualXP environment in the USB prefs or not ... I've tried it both ways - doesn't matter. The only resolution thus far is totally rebooting the Mac. Shutting down Windows XP and rebooting Parallels does not resolve it - only a full Mac reboot resolves it. I've made a YouTube video with a full screen capture to show exactly what is happening. Hope I've been thorough enough in my explanation - I'm hoping someone here can help: YouTube ScreenCast: http://www.youtube.com/watch?v=2jYYYrO4j14 Thanks in advance for your help
