Input Sources and USB Pairing

To ensure that your Input Source is correctly paired to the right USB Upstream port. If the Input-USB pairing is not done properly (for example HDMI 1 with USB Upstream 2), you cannot access your USB port.

See the following Input Source and USB Upstream pairing table for proper pairing. (See Figure 4.)

Touch functionality follows the Input source and USB Pairing. That is if using HDMI 1 as Input the USB 1 has to be used as upstream port to achieve touch screen functionality, USB 2 for HDMI 2, and so forth.
