About to upgrade my handheld OS with VMware. Have people had luck doing this?? I set the guest to automatically take USB devices when it has focus and disabled MissingSync from automatically opening when a device is plugged in..... Pretty sure that should do it, but I remember attempting this years ago and ran into an issue during the restore phase where the Mac host would not release the BB to the Windows guest.
I think the older builds of Parallels were problematic. I'm using the most current release and while I have no need for and OS update though the present release I'm using should be fine.
