[SOLVED] Unable to mount USB, not showing up in lsblk

When I run lsblk -f to mount the device it is not showing up.

sda                                                      
├─sda1 ext4         61025ca3-7e81-4045-b4c5-1d021bfac5c8 /
├─sda2 ext4         c390cfbd-ba5b-4cb4-be6d-2338754ab465 /home
└─sda3 swap         54325b79-165e-4f7b-835e-f270b8de64e7 [SWAP]
sdb                                                      
├─sdb1 ext4         2c225928-f839-465d-a16e-ffd0eac68abb 
├─sdb2 ext4         71f1c3c1-8f59-463c-87b3-a97dc11eaf55 
├─sdb3 ntfs         1942538067BE10B7                     
└─sdb4 swap         c4ec35ac-dd65-470a-b9e0-d035ef8edd03 
sr0

Although when I check journalctl and dmesg I do find that it has been detected.

Oct 10 17:11:04 lordran kernel: usb 10-3: new high-speed USB device number 4 using ehci-pci
Oct 10 17:11:12 lordran kernel: usb 10-3: USB disconnect, device number 4
Oct 10 17:11:13 lordran kernel: usb 10-4: new high-speed USB device number 5 using ehci-pci

[ 5942.482695] usb 10-4: new high-speed USB device number 5 using ehci-pci

Im not sure what the issue is. I have tried the usb on several usb ports and it still continues to do the same. The usb also works on other computers, and I have tested a different usb as well to see if maybe there was a problem with the one I need to mount, but it is having the same issue as well. Any help would be appreciated.

It showed that a device was (dis)connected, but it doesn't acknowledge what class the device is.  What does lsusb show?

Bus 010 Device 006: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) Flash Drive
Bus 010 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I went ahead and disconnected and reconnected the usb. The last line dmesg gives me is...

Didn't see the hub.  May try to skip the hub to see if does something different.

Thing is I don't have a usb hub. It's connecting directly the back of my pc. So im not sure why it thinks it's a hub as I dont have one connected.

It is a root hub that any and all usb devices and other usb hubs connect into.

Did you get a kernel update recently (during a "pacman -Syu")? Did you reboot after the kernel update?

I did just do an upgrade less than an hour ago. I'll reboot and hopefully that'll fix everything.

EDIT: Yup that was it. Damn I feel dumb.

Re: [SOLVED] Unable to mount USB, not showing up in lsblk

I've found my answer here: Just reboot!
I think I am so used to the update, when finished, never asks me to reboot, contrary to Windows, that I think that it's unnecessary. but it's not... (at least for kernel upgrade of course)
