 - Make sure `dwc2` (or `dwc3`) driver is previously loaded on capable device, and configuration is set to **OTG peripheral** mode: this may be driven by hardware (including cable) and/or software.\
 (on supporting Pi devices, just add `dtoverlay=dwc2,dr_mode=peripheral` in `usercfg.txt` (or `config.txt`) to force both by software)
 - Plug USB cable into host Computer port before booting device.
