I was having some problems booting into Ubuntu. After trying to reboot for sometime, I eventually opened the 4.4.0-31 recovery mode. while it was booting into recovery mode, it said that /dev/ubuntu-gnome-vg needs to fsck manually.

While this was going on the touchscreen for the computer was connecting and disconnecting repeatedly.

The screen was showing this: 

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.

and then this repeats with the device being 43.

How do I stop this so that I can actually try and fix the problem on the disk. Also if you guys have some advice regarding /dev/ubuntu-gnome-vg needing to be fsck'd that be great.

A faulty cable might cause this.

It might also be a power problem. I've had better luck with some USB thumb drives since switching to a powered USB hub.

This looks suspiciously similar like a broken USB cable or port. I can say that for sure because I'm using such: every time I'm touching a cable of my USB hub, I see in /var/log/syslog a wall of those messages about (dis) connection, and increasing device number; and the connected mouse resets its sensitivity.

Just for the record, here's an example of mine log:

Temporarily disconnect your touchscreen device from its USB port. Then boot the computer into RECOVERY mode from the GRUB menu, choose ROOT, then type sudo fsck -f /dev/ubuntu-gnome-vg. Let us know how that works. Cheers, Al
