@moses_izumi I assume it's related to PMIC or detection. I don't own any SDM845 devices, but on SDM710 it works... but requires manual switching and powered device. If you patch USB node in devicetree to be dual-mode and have role-switch property, then issue manual switch it should work (after all it's just a designware usb controller): https://wiki.postmarketos.org/wiki/Qualcomm_Snapdragon_710_(SDM710)#USB It's possible that PMI8998 would even enable VBUS, but it likely would need a manual GPIO toggle to do so or something but again, I haven't worked on that PMIC/SoC so I don't want to mislead anyone
