I want to create custom expansion board with two host USB ports for two non-removable usb cameras.
On my board i connect USB2_ID_PMIC to ground, but nothing happens, no new devices on bus, only camera on USB2_1 port. What i'm doing wrong?
Thanks for reaching out!
Perhaps what you can try to apply a simple USB hub to the USB port that you've successfully used. I'm referring to something similar to what is discussed at https://forum.allaboutcircuits.com/threads/simple-2-port-usb-2-0-hub.72097/.
Maybe this approach works better for your project.
Please note that custom boards are of the scope of the support. Anyhow, we'll do our best effort to help you in case you continue to experience issues on your design.
