   Is that tape normally used for repairing large string instruments? :-)

   (I have one USB stick with the common swivel cover - swings round the   
   provide a metal cover over the connector, or did until I [I don't   
   remember how] partly pulled the PCB out of the plastic body [the cover   
   now doesn't extend enough to cover the connector]. Until I accidentally   
   did that, I was unaware there was an LED on the board at all, but there   
   is [it's red, and I think stays on all the time the unit is plugged in].   
   I just wonder why they bothered fitting an LED that would normally never   
   be seen; all I could think of is that this particular PCB is fitted to   
   more than one type of body, and in one body it _is_ visible.)
