Connect via USB?

The manual states that IC Pro can connect to any computer. My desktop PC do not have WiFi, so this means it can connect via the USB, correct?
(I’ll probably get the iPad version)

As long as you have a router in the middle you’ll be good to go.
iPad connect to router via Wifi
Desktop/Laptop without wifi connect to router via ethernet.
I personal have had problems running bonjour v2 which is the link Steinberg points users to on apples website. If you do encounter connections problems then download itunes from apples website, this install with carry bonjour v3.XX. Make sure you use the Desktop version and not the windows store version.

Hope this helps
