    Hi ,

    We haven't met the damage when U disk plug in.  If possible the spike voltage during plug in  maybe the reason.  The another reason maybe the ESD protection level in the U disk is poor. What is the application output cap of the type A port ? 

    In the BC1.2 SPEC the min cap value should above 120uF. Pls. double check the output cap is big enough ,thanks!
