Prolific based USB to Serial adapters not supported.

I've been trying to use the following Usb To Serial Adapters (Aluratek and TrendNet S2) in my projects for communicating with different maritime sensors. I'm finding that I'm not able to read the data that is transmitted from those sensors and after investigating VBox.log I've found a critical error has been logged. However, I do have other Usb To Serial adapters, one by TrippLite and another based on CH340 chipset and both work great but I would prefer to use my TrendNet adapters as they support higher baud rates.

I've attached the VBox.log to this post.

You need to update the extpack. It must match the installed version of VirtualBox for USB2 devices to work.

I'm sorry I should have mentioned I'm not using USB pass-through. My intention is to use VXWorks as a client OS and access the serial addresses directly. For this demonstration I used Windows XP to test the serial ports back to back with a null modem to verify I was able to TX/RX on both serial ports. My goal is to try and move away from a hardware simulator and use a virtual simulator instead when developing my software.
