Some one posted about this device not long ago (I can't find it however) they were having trouble getting it connected, IIRC.
I just bought a Micromys V3, and I love it. This one allows connecting just one mouse - ether ps2 or most USB. I understand the V4 may even be more compatible. I like these because it will work with both Amiga and C-64/ 128 machines. Apparently the plug is too large for the Amiga A600 though, (and the C-128) requiring an adapter or trimming.
Hope this helps.
