Hi support, I found a problem about USB Bluetooth in Parallels Desktop 3.0.5584. I am using a bluetooth mouse and I need to use bluetooth to sync between guest Windows and my Windows Mobile phone. Every time when I attached the built-in "Bluetooth USB Host Controller" to the guest Windows, my mouse was disconnected. I just thought Parallels cannot play the device on both sides. Since I don't want to use USB mouse so that I bought a USB bluetooth adapter. I just thought I could connect my bluetooth mouse to the built-in BT controller and let Windows use another USB adapter and then the two BT devices should work separately. Unfortunately, when I connected the USB BT adapter to my Macbook, my mouse also disconnected automatically until I pulled the adapter out. And I tried to set the VM settings to "Connect to Mac OS X" and "Connect to Guest OS", same results. But to my surprise, VMWare Fusion can do it well. I tried Fusion 1.1.1 and found if I set it to "Connect to Guest OS", the new adapter would never cause my mouse disconnected when I plugged it in or pulled it out. But I don't like Fusion. I found its performance was not as good as Parallels. And because I like Parallels features such as synchronizing users profiles. I just want to report this problem to you and hope you can fix it in the next version. Thanks in advance.
