Prblem whit USB in FreeBSD 8

Hi *

I'm running FreeBSD 8 i386 on my machine X2 AMD Athlon 64, I have devices
such as USB keyboard and mouse, which works perfectly, but as to the
pendrive, I had some problems when I connect my pendrive Fujitel for 1GB
recognizes this, but will not let me do anything, I can open applications,
etc. loggin a console, I managed to do the dmesg when connecting:

  (da0: UMass-sim0: 0:0:0): lost device
(da0: UMass-sim0: 0:0:0): Synchronize cache failed, status == 0x39, scsi
status == 0x0
(da0: UMass-sim0: 0:0:0): removing device entry
GEOM_LABEL: Label msdosfs / [you: Qiufo] removed.
umass0: detached

Can onlydisconnect  hold back my system, any thoughts on this? thanks in
advance
