Once he has been identified, is flashing or nothing - unless that data is written on it (EIM reading, however, the LED is off). That the protective cap hard going, I can not confirm, but it depends in which USB port you put the Cruzer Fit.

Unfortunately, no trailer is - which has given me better fallen at Transcend.
Conclusion: Due to the poor write speeds and not supplied trailer there two star deduction.
