Although no native drivers for Windows 7, this seems to work.
1. Download Ver.3.110.0513.2004 http://homedownloads.cisco.com/downloads/driver/WUSB11v4_08272004_dr_0.exe
2. Extract the files to temporary folder.
3. Let windows detect device and tell you it can't find any drivers.
4. Open up device manager and tell it to update from the temporay folder, making sure to let it search sub folders.
It "should" be detected as USB11 ver 2.5.
