Gau*_*shi 6 boot usb fsck recovery-mode disconnect
我在启动 Ubuntu 时遇到一些问题。尝试重新启动一段时间后，我最终打开了4.4.0-31恢复模式。当它启动进入恢复模式时，它说/dev/ubuntu-gnome-vg需要fsck手动。
当这种情况发生在计算机的触摸屏上时，会反复连接和断开连接。
屏幕上显示的是这样的：
usb 2-7: new full-speed USB device number 42 using using xchi_hcd
usb 2-7: New USB device found, idVendor=04f3, idproduct=016f
usb 2-7: New USB device strings: Mfr=4, Product =14, SerialNumber=0
usb 2-7: Product: Touchscreen
usb 2-7: Manufacturer: ELAN
usb 2-7: ep 0x2 - rounding interval to 64 microframes, ep desc
says 80 microframes
usb 2-7: USB disconnect, device number 42.
然后设备号为 43 时重复此操作。
我该如何阻止这个问题，以便我可以实际尝试修复磁盘上的问题。另外，如果你们对 /dev/ubuntu-gnome-vg 需要进行 fsck 有一些建议，那就太好了。
这看起来与损坏的 USB 电缆或端口非常相似。我可以肯定地说，因为我正在使用这样的：每次我触摸 USB 集线器的电缆时，我都会在墙上看到有关（断开）连接和增加设备编号的/var/log/syslog消息；连接的鼠标会重置其灵敏度。
只是为了记录，这是我的日志示例：

暂时断开触摸屏设备与 USB 端口的连接。然后从 GRUB 菜单将计算机引导到恢复模式，选择 ROOT，然后键入sudo fsck -f /dev/ubuntu-gnome-vg。让我们知道它是如何运作的。干杯，艾尔
