I'm looking to connect an Arduino to a phidget, specifically the MOT0110. How do I do so? I know that Arduinos have an USB breakout board, but preferably I can use the raw data without going through a USB.
I'm afraid it's not supported. The MOT0110 does have a VINT port (internally a UART), but the protocol is proprietary and undocumented. You could refer to the phidget22 source to decipher the USB protocol.
