The short answer is that this is a known issue and your dongle probably won't work with CrossOver.
For the most part, CrossOver relies on the host operating system (Mac OS X or Linux) for access to hardware devices. If the host OS doesn't have a driver for the device, then Windows programs running under CrossOver won't be able to make use of it.
The Windows driver software for the dongle won't help. You can imagine the software world as a series of layers. On top are the applications. They sit on the operating system. The OS sits on drivers, which sit on hardware. Now, ordinarily, Windows applications don't "fit" on top of Mac OS X or Linux. So, CrossOver inserts itself as another layer just below the applications and the host OS, as an adapter which makes the two fit together. However, CrossOver makes no attempt to insert itself between the OS and the drivers on which it relies. That's a completely different layer.
So, while the installer for the Windows driver may succeed, the driver itself is not used and does not help the host OS interface with the hardware.
Sorry I don't have better news for you. Thanks for trying CrossOver.
P.S. Just so you know, this particular forum within our forum system is for unsupported builds of CrossOver (like our build for Solaris, for example). You probably wanted the CrossOver Mac
or CrossOver Linux
