What phones are compatible with this charger?

I have this dock/charger here, but I don't know what model is compatible with it.

It is a dock with two connectors side by side, micro USB and HDMI.

I know the XOOM tablet has those exact two connectors, but it is NOT compatible. I tried. The Xoom charges through yet another connector, that this dock does not have.

I really want to know what phones are compatible with it. Not just charging it, but also using the USB, HDMI and automatic desk clock features, as indicated by the manual. Sadly, the manual does not say what models are supported, neither does the Motorola website.

I bought it by mistake and intend to sell it, but you know what, I am considering buying a new phone, I have a Sony and I am not happy with it, I think I'm going to buy a Motorola this time.
