Use a Keyspan USB-to-Serial adapter with Virtual Box
Authored by: ehunt123 on Jul 29, '08 08:48:48AM

The Keyspan adapters are known to work well with non-Windows environments. In addition, there are many other adapters that tend to work with OSX and Linux, but no list is complete nor available. Here are some tips that might seem common but are good strategies if you have an adapter and want to get it working on the Mac or are looking to purchase one:

First, you need to find the chipset inside of the adapter. This is the critical thing since I have yet to see anyone who builds their own. From what I recall, most adapters use the same two or three chipsets found in the popular and working ones like Keyspan and IOGear.

Second, take the chipset name and run it via Google. You might come up on a few SourceForge Projects working on creating Linux and OSX drivers for those adapters. Both list a sample of the products they are in, but might not be complete. If I know that the Keyspan and IOGear contain the "Prolific" chipset that powers the majority of these and that it has both drivers and success reported from some reading.

If this is not known or you cannot identify it because it is not listed, I would run the product name and number through Google. This could point you in a good direction or provide the information needed in order to get a working driver.
