Reply to what usb speed is all my gear?

Just been reading an article on usb hubs and ive ordered one which is a Belkin F5U307 USB 2.0 7 Port Plus Hub, now in the article it says not to mix the 2 different speeds 1.0 & 2.0, so how can i find out what my speeds are for the following gear?

Wd external hd 2.0?
audio8 soundcard 2.0?
vestax vci-100 1.0?
kontrol x1's 1.0?

am i correct with those speeds or if not can some on pls tell me what they are?
thanks Paul
