Like it is suggested below when it is loaded thru an extension file ? Is this driver provided directly by the Mac OSX kernel ? In such a case, how to disable it

I scanned carefully any ist file into this tree and found no sign of the Prolific driver. The USB driver shows up into the USB device list (into Mac OSX system profile),īut there is no such extension file mentioning the Prolific driver under the /System/Library/Extensions tree. Indeed, when I plug the relevant USB device, instead of showing up under the Windows XP guest system, I am running Mac OSX 10.5.7, and the Prolific USB-serial driver seems to be preinstalled I currently have the same kind of issue, but the fix suggested below can't be applied.

Virtual Machine menu then USB then Connect Prolific USB-SerialĬontroller.

When I had done this I returned to my VMWare VM and clicked on the
