Are all bluetooth adapters the same?

Solution 1:

Are all bluetooth adapters the same ?

No, there is quite a variety of different bluetooth standards:

Bluetooth: Specifications and features

Some, but not all, are backwards compatible to certain standards.

Update

The V470 Cordless Laser Mouse is compatible with multiple BT standards and so is the EB-MDC1, so there's a great likelihood for a match. :)

Solution 2:

There are many different Bluetooth adapters, many have different chipsets and specifications (such as speed, distance (Class) EDR support along with other things).

However, if your mouse follows a set standard that the new Bluetooth adapter supports, it should work without problems.

I have used a generic Bluetooth class 2+EDR adapter (I think the most common/cheapest) with off the shelf Bluetooth mice and not had a problem.

Edit

Update to your edit -

It Should work fine with that one... class and various other things mainly affect the speed, distance and a few other technical things (such as pairing) that the device uses. Actually supporting devices should be no problem, depending on the software stack you use (Blue Soleil, Toshiba, Microsoft etc.) - The mouse should simply support the profile "HID / Human Interface Device) and work with any 1.2+ Bluetooth hardware or software stack out there.
