i have problem with random disconnecting(disconnect and connect again -  LJ blink and Windows makes "USB connect" sound) of U6. Sometimes once per hour and sometimes once per a day. LJ is connected with "first-class" 1m USB cable (i tried different cablest too) and it is closed in metal enclosure. 


I tried solder SMD capacity (47uF, 35V - from drawer) beween VUSB and GND  (C93? - not readable) and it seems solved. On the board are another free component places.


Please, do you have a some ideas where add components for better stability?

A couple quick initial questions:


1.  Does this issue go away if you have not connections to the U6 ... except USB?


2.  Does the U6 recover on its own, or do you have to power-cycle the U6 or something else?
