I happened to try my H700 this afternoon, with an IOGEAR bluetooth dongle on an Acer tablet PC. The computer found the H700 immediately, pairing was simple and connection was automatic. Based on this experience, I don't think you'll need a driver.
This also helped me with an HP Compaq 6710b and Windows 7. Despite loading all the windows updates and having recognised the H700, the system failed to "find" the correct driver but your link worked perfectly. Thanks so much!
