This USB stick either provides broken data or udev helpers fail to read it.
See the broken by-id symlink.
 I think this did not happen in August when I used it last.

Also lsusb lists it as 2GB device, while in fact its 8GB:

Bus 001 Device 003: ID 0930:6544 Toshiba Corp. TransMemory-Mini / Kingston
DataTraveler 2.0 Stick (2GB)

Perhaps the vendor reused the ids for several devices...
