Very old thread but I resolve the same issue on Ecoquiet 630's and 780's by doing the following;
It may be that the Microsoft driver contained within Windows 7 constantly takes precedence over any other driver that is later installed to the system.
Once the RM driver has already been downloaded from their site and unzipped to the C:\RM folder, but before going to SetUp
1. Through Device Manager identify and then uninstall the current driver.
2. Go to the driver location, C:\Windows\system32\drivers\usbvideo.sys.
3. Copy the driver to a flash drive for back up.
4. Take ownership of the file from Trustedinstaller and set full control to Administrators.
5. Delete the driver from the System32 folder.
6. Install the Bisoncam driver and reboot.
The RM driver is allocated for Vista in a lot of instances, but it is not usually necessary to run it in compatibility mode.
