The software suite you get with this is rubbish, so you go to the Mitsumi site for an update, right? They have the Widcomm suite there which is infinitely superior but guess what? You install it and IT DON'T WORK! The problem is the file btwusb.inf has no mention of mitsumi in it, and therefore will not recognise your dongle once installed.
This is what you have to do
1. Download widcomm bluetooth suite 220.127.116.11 from here

DriverGuide.com - Using DriverGuide's Installer
DriverGuide's installer software (Windows only) simplifies the driver installation process. It safely downloads and verifies your driver and then assists in the installation of it.
You may notice that the file size of the installer software is much smaller than the file size of your actual driver. The reason is that first the installer setup file is downloaded, and then the installer software does the work of fetching
your driver from our fastest download server.
The installer setup file has been certified safe by leading-class virus and malware scanners.
Sometimes anti-virus software can report false positives. If this happens to you, we encourage you to submit the file you download to VirusTotal (a free, independent service which identifies malicious content) where you will see dozens of other anti-virus scanners report the file is perfectly safe.
The installer setup file may include a purely optional advertising offer which you are free to decline. We only work with trusted advertising partners.
Note: Windows only. Mobile, Mac OS and Linux users can choose other download options by deselecting the installer checkbox below the download button.
