Hello linux-usb community, I am new to linux-usb code and I hope that my question is not silly. I am interested in real-time usb. I know that on USB3, the gadget can initiate transactions and I am searching for the function that is called in the usb3 host when an USB3 gadget wants to start a transaction. For example for raspberry pi 4 or other host. Is it on the xhci host code or on the USB3 controller code (for example dwc3) ? Do you have any hints? I appreciate any help. Thank you, Laurentiu-Cristian
