USB disk not getting a device (sdb)

I have a hardware problem with my N100 mini-PC, when I plug in a USB storage device, I don't get a device (/dev/sdb for example). Here is the relevant output of my dmesg:
```
[ 2268.454083] usb 1-2: new high-speed USB device number 10 using xhci_hcd

```

What should I do or check?

Re: USB disk not getting a device (sdb)

Basic check, `uname -a` and `pacman -Q linux`, substituting the name of the kernel package you're using if not 'linux'.

If they don't match, reboot.

Re: USB disk not getting a device (sdb)

Thank you so much!
A reboot did it; I indeed did an update just before and hadn't rebooted yet.
