[SOLVED] lsblk doesn't list USB block device

I'm trying to connect and mount an USB MP3 player (with 64gb SD card inside it), however

 lsblk 

only outputs the following:

NAME                   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda                      8:0    0 931.5G  0 disk 
├─sda1                   8:1    0     1G  0 part /efi
└─sda2                   8:2    0 930.5G  0 part 
  ├─VolumeGroup00-root 254:0    0   300G  0 lvm  /
  ├─VolumeGroup00-swap 254:1    0    10G  0 lvm  [SWAP]
  └─VolumeGroup00-home 254:2    0 620.5G  0 lvm  /home
sr0                     11:0    1  1024M  0 rom  

Upon disconnecting and reconnecting the device,

  dmesg 

outputs this:

[34063.959613] usb 1-1: USB disconnect, device number 15

From that it's obvious that it registers the device.

On my other machine (also running Arch but not running LVM), the player get's recognized as block device right away:

  lsblk 

NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk 
├─sda1   8:1    0   450G  0 part /
└─sda2   8:2    0  15.8G  0 part [SWAP]
sdb      8:16   1  59.8G  0 disk 
sr0     11:0    1  1024M  0 rom

(see the sdb entry)

Any ideas?

Re: [SOLVED] lsblk doesn't list USB block device

Check

pacman -Q linux && uname -a

if the versions don't match you'll have to reboot as your running kernel and the installed kernel have diverged (adjust the pacman -Q command relevantly if you use other kernels). Installation of a kernel removes the old kernel's modules and one should ideally reboot into the new kernel as soon as possible.

I ran the command, kernels differed. Rebooting has solved the issue. Many thanks.
