~设备不在手边,可以试试定制USB驱动,以下的步骤我在台式机上测试过(使用hackintool无法检测typec)~ step 1 use SSDTTime to dump the system DSDT in Windows or Linux
step 2 use SSDTTime to patch out SSDT-USB-Reset.amlfrom origin DSDT
step 3 use USBMap to discover ports and test all USB ports with usb2 and usb3 devices step 4 change usb type in USBMap(3: USB 3.0 Type-A connector; 9: typec-sw) step 5 build out USBMap.kext in USBMap and disable SSDT-USB-Reset.aml in config.plist

测试了 type-c 转 RJ45 无法热插拔,type-c 转 HDMI 可以热插拔
应该和供电有关,尝试了IOElectrify等方法都没能解决
SSDT中关于雷劈3的UID是空的
