I will follow my u-boot theory ... okay there is no influence of u-boot. If i boot directly from the RPi Bootloader it shows the same behavior. I did the following test cases with enabled debug: 1. boot RPI Zero (OTG configured per DT) without anything connected to the OTG port 2. boot RPI Zero (OTG configured per DT) only a OTG cable connected to the OTG port test case 1 (nothing connected, no issue): dwc2 20980000.usb: mapped PA 20980000 to VA dc850000 dwc2 20980000.usb: registering common handler for irq33 dwc2 20980000.usb:
