Question

我想在我的Nexus 5中构建一个Android图像，但adb设备无法检测到它。我想我的笔记本电脑有USB问题。当我插入设备时，它没有连接。以下是我用Google搜索时建议的各种命令的一些输出：

lsusb -t：

/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/9p, 480M

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M

|__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M

sudo fdisk -l </ p>

dmesg |尾巴⇒插上usb⇒dmesg| tail -n 20：这是前两个命令之间的区别：
