I assume it did not get updated to 2.6.16 as it works there. I ran the ICON Dimmer add test on 1.60 (latest V1 image) and get the same results you have. The device is added with a type of OTHER. Only suggestion I can offer is to go the latest V2 image. Since it fails on 1.60 and that is the last V1 image going to V2 is the only path. If you do go to V2, install the latest Java Discovery tool first and use it to install the latest V2 image.
