Inserting USB disk does not create block device

I've just upgraded from Slackware64 14.2 to -current, and now when I plug in a USB drive it does not create a block device so I can't mount it.

lsusb lists the drive, and kernel messages note that the drive has been detected:

Code:

Udev is running and so is messagebus. blkid doesn't display any information on the drive at all. Anybody have any ideas on what I'm doing wrong?

There normally should be something about the partitions ON the stick after that, like this

Code:

scsi 5:0:0:0: Direct-Access     ATA      WDC WD10EADS-00L 01.0 PQ: 0 ANSI: 5
sd 5:0:0:0: [sde] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB)
sd 5:0:0:0: Attached scsi generic sg6 type 0
sd 5:0:0:0: [sde] Write Protect is off
sd 5:0:0:0: [sde] Mode Sense: 00 3a 00 00
sd 5:0:0:0: [sde] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA
 sde: sde1
sd 5:0:0:0: [sde] Attached SCSI disk

Could it be that you haven't loaded the usb-storage kernel module?

It looks like my kernel modules are snafu. Somehow my kernel is a different version to the kernel modules I have installed.Thanks for pointing me in the right direction!
