 I have the same problem in FreeBSD 7.0-REL with the following USB key:
 
 $ usbdevs -v
 ...
 port 2 addr 2: high speed, power 94 mA, config 1, Store'n'go(0x0020), Verbatim(0x08ec), rev 2.00
 
 which only works (fine) when plug'ed in at boot time:
 
 da0 at umass-sim0 bus 0 target 0 lun 0
 da0: <VBTM Store'n'go 6.51> Removable Direct Access SCSI-0 device 
 da0: 40.000MB/s transfers
 da0: 3812MB (7807999 512 byte sectors: 255H 63S/T 486C)
 
 if you plug it in later you will get:
 
 Aug  6 10:19:36 rebelion kernel: da0 at umass-sim0 bus 0 target 0 lun 0
 Aug  6 10:19:36 rebelion kernel: da0: <VBTM Store'n'go 6.51> Removable Direct Access SCSI-0 device 
 Aug  6 10:19:36 rebelion kernel: da0: 40.000MB/s transfers
 Aug  6 10:19:36 rebelion kernel: da0: Attempt to query device size failed: UNIT ATTENTION, Medium not present
 
 and the devices /dev/da0s* does not show up; you only may access
 /dev/da0 with fdisk(8) or even with dd(1);
