When I plugged in my USB storage device it was recognized as a USB device but not recognized as a storage device, it was never assigned a device.
I saw messages like:
[ 154.708000] usb 5-3: new high speed USB device using ehci_hcd and address 4
[ 154.852000] usb 5-3: configuration #1 chosen from 1 choice
But it was never assigned a device.
I rebooted the machine and it now was recognized as a storage device, but not mounted, when attempting to mount it manually I did:
sudo mkdir /media/sdb1
sudo mount -t auto /dev/sdb1 /media/sdb1
mount: you must specify the filesystem type
Then I did
sudo mount -t vfat /dev/sdb1 /media/sdb1
and it mounted normally.
