Do you get any error message?
Did you ran it in verbose+hash mode?
Did you try copying any other file to USB drive? What was the result?
Do you see any errors in the log files /var/log/faillog and /var/log/messages ?
Run cp command as follows and let us know how far it goes:
cp -arv /source/filename /destination
use . instead of filename if there are many files that needs to be copied.
