Mac OS X 10.5.1
Vmware Fusion 1.1
Guest OS: Windows XP Pro US SP2
Machine: Mac Mini Core 2 Duo 1.83GHz / 2GB DDR
Driver version: 0.3.0

When the driver is loaded, it prevents Vmware Fusion to take ownership of the driver: when the "Connect Prolific USB-Serial Controller" is selected from the Vmware menu, no error is reported but the guest OS does not detect the device, and the Vmware menu is left unchanged - whereas the item changes to "Disconnect Prolific USB-Serial Controller" when the VM is able to take control over the device.

Once the driver is uninstalled, everything works fine.

It works well though with Mac OS X 10.4.10 (on a MacBook Pro) and VmWare 1.1beta.

    To unload the driver, you may use the following command:

    sudo kextunload -v -c nl.bjaelectronics.driver.PL2303 /System/Library/Extensions/osx-pl2303.kext

    This also occurs when trying to connect to Parrallels. Parallels isn't so kind as to tell you what application is holding the USB to Serial device. Unloading via

    kextunload /System/Library/Extensions/osx-pl2303.kext/

    Works, but is a pain.
