Hi

Can you not boot from internal flash instead of USB ? it looks like its having an issue reading it , maybe the format that the USB is in is incorrect , what format is it currently set to ?

The USB flash is "shorting".  The pins are not contacting each other.  The moulding of the USB flash itself is preventing this.  Get a file and shave off the moulding or try a different variety of USB flash.  

Try one of this (image below).  Maximum size 16 Gb.
