Do you still need Bluetooth 4.0 to use Magic TrackPad 2 with an older Mac if you use it wired?

[iMore Question]

I understand that the new Magic TrackPad 2 requires Bluetooth 4.0 support on your Mac. I have an older iMac and am curious if I use it as a wired device does it still require the Bluetooth 4.0 connection to function properly?

I doubt it.

On a lark, I decided to buy the Magic Trackpad 2 to test it out on my 2009 iMac. Surprise, it works just fine, wirelessly, despite the Mac not having Bluetooth 4.0. According to the system report, Bluetooth LMP version is 0x4, and anything with Bluetooth 4 should read at least 0x6 or higher.
