我购买了一台全新的 Acer Swift 5 笔记本：SF514-54GT。它采用了全新的英特尔第 10 代 i7-1065G7 芯片和 NVIDIA MX250 GPU。非常强大。
尝试热插拔 HP Thunderbolt 3 G2 扩展坞时，它会正确检测外部屏幕 (DP) 并授权扩展坞：
root@qdrop-swift5:/home/qdrop# boltctl list
● HP Thunderbolt Dock G2

但是，USB 设备和 NIC 根本无法识别。在启动前连接底座时，一切正常。

此外，笔记本电脑无法充电 - 即使 G2 也应该支持充电。我该如何解决此问题？
注意：安全启动已禁用。我在 BIOS 中没有更多有关 Thunderbolt 安全性的设置。
任何帮助都非常感谢。如果有帮助的话，我也可以向您发送日志。只需告诉我如何获取它们即可。
